Machining Fundamentals
2.1 Fundamentals of Positioning 2.1 Fundamentals of Positioning Position encoders and reference marks The machine axes are equipped with position encoders that register the positions of the machine table or tool. Linear axes are usually equipped with linear encoders, rotary tables and tilting axes with angle encoders. When a machine axis moves, the corresponding position encoder generates an electrical signal. The CNC evaluates this signal and calculates the precise actual position of the machine axis.
2.1 Fundamentals of Positioning Reference system A reference system is required to define positions in a plane or in space. The position data are always referenced to a predetermined point and are described through coordinates. The Cartesian coordinate system (a rectangular coordinate system) is based on the three coordinate axes X, Y and Z. The axes are mutually perpendicular and intersect at one point called the datum. A coordinate identifies the distance from the datum in one of these directions.
2.1 Fundamentals of Positioning Designation of the axes on milling machines The X, Y and Z axes on your milling machine are also referred to as tool axis, principal axis (1st axis) and minor axis (2nd axis). The assignment of the tool axis is decisive for the assignment of the principal and minor axes.
2.1 Fundamentals of Positioning Setting the pole and the angle reference axis The pole is set by entering two Cartesian coordinates in one of the three planes. These coordinates also set the reference axis for the polar angle PA. Coordinates of the pole (plane) Reference axis of the angle X/Y +X Y/Z +Y Z/X +Z Absolute and incremental polar coordinates Absolute polar coordinates always refer to the pole and the reference axis.
2.1 Fundamentals of Positioning Angle Measurements Polar measurement of angles is referenced from the 3 o'clock position (0 degrees). Positive angles rotate in a counterclockwise direction; negative angles rotate in a clockwise direction.
2.1 Fundamentals of Positioning Absolute and incremental work piece positions Absolute work piece positions Absolute coordinates are position coordinates that are referenced to the datum of the coordinate system (origin). Each position on the work piece is uniquely defined by its absolute coordinates.
2.1 Fundamentals of Positioning Setting the datum Fixture Offsets A production drawing identifies a certain form element of the work piece, usually a corner, as the absolute zero datum. When setting the datum, you first align the work piece along the machine axes, and then move the tool in each axis to a defined position relative to the work piece. Set the display of the CNC either to zero or to a known position value for each position.
2.1 Fundamentals of Positioning Example2: SetZero See "Absolute Zero Set" on page 138 for more information on using the SetZero cycle. The work piece drawing shows holes (1 to 4) whose dimensions are shown with respect to an absolute datum with the coordinates X=0 Y=0. Holes 5 to 7 are dimensioned with respect to a relative datum with the absolute coordinates X=450, Y=750.
2.2 Manual Machine Positioning 2.2 Manual Machine Positioning Jog Mode Moves You can make or change jog moves when the CNC is in Manual Data Input Mode, Teach Mode, or in the Tool Page; and the servos are on. Jog Mode Description Rapid Default rapid speed for continuous jogs. Actual speed determined at machine setup. Feed Continuous jog at feedrate determined at machine setup. Jog: 100 Conventional Jog Mode, increment set to 100 times machine resolution.
2.2 Manual Machine Positioning Adjusting the Feedrate The Feedrate Override rotary switch can be used to override the currently active feedrate or rapid rate for machine moves. The switch provides a range of 0% to 150%. Setting the switch to 100% will allow the actual feedrate or rapid rate currently active to be used. The machine builder determines the default rapid rate and maximum feedrate at setup. If the CNC is shut down, the configuration file reloads these default rates at the next power-on.

Manual Data Input
3.1 Manual Data Input (MDI) 3.1 Manual Data Input (MDI) Overview Manual Data Input allows data input for simple machining operations. Manual operation, single step operation, and single commands can be entered. The following describes the concepts, and formats used with the ACU-RITE 3500i CNC. These topics are being introduced in this chapter.
3.1 Manual Data Input (MDI) Manual Data Input Mode Settings Features (or settings) that remain active for more than one operation are referred to as modal. Modal features remain active until you change or cancel them. Most CNC functions are modal. As an example, if the CNC is in Rapid Mode, it executes all moves at the rapid rate until you initiate Feed Mode. The CNC can be in several modes, as long as the modes do not conflict. Before making a manual move, make any necessary mode settings.
3.1 Manual Data Input (MDI) Manual Data Input Menu Bar The following table describes the bottom bar menu buttons. Button Function Mill Line opens the Mill Line pop-up dialogue where information can be entered to mill a line. Mill Arc opens the Mill Arc pop-up dialogue where information can be entered to mill an arc (or radius). Drill Cycles opens a sub menu for selection of type of drilling cycle, e.g. Basic, Pecking, Counter Bore etc.). Selection of a cycle opens a form for data input.
3.1 Manual Data Input (MDI) Draw & Manual bottom menu bar buttons. Button Function Touching the Draw button will view real time drawing of the work piece as it is being machined. Manual button when touched will cancel the program. MDI Menu Page two The following table describes the bottom bar page two menu buttons. Button Function Record is used to toggle between recording all Manual Data Input commands entered in standard MDI. If record is on, all commands successfully run will be recorded.
3.1 Manual Data Input (MDI) Manual Data Input Operations The following explains a few of the machining operations that are available with Manual Data Input.

4.1 Tool Table Feeds & Speeds Table Feeds & Speeds Overview The Feeds & Speeds Table allows the user to enter additional tool data for each tool so that the control can calculate Feeds and Speeds to be used in MDI (Feed and Speed MDI Touch Screen Feature Dialog) or programs. Based on the Tool Diameter and Tool Length as well as other entered tool parameters the Spindle Speed, Rough Feed and Finish Feed can be automatically calculated for each tool.
4.1 Tool Table Data can be entered based on the Tool Diameter and Tool Length as well as other entered tool parameters the Spindle Speed, Rough Feed and Finish Feed can be automatically calculated for each tool in the Tool Table. Column Description Tool Number Number of the tool corresponding to the Tool Table. Tool Diameter Compensation value for the tool diameter (from Tool Table). Tool Length Compensation value for tool length (from Tool Table).
4.1 Tool Table Using the Feeds & Speeds Table The 3500i can calculate spindle speed, rough feed and finish feed for each tool. ๏ To calculate the spindle speed enter the tool's diameter and the desired surface speed. The initial diameter shown is from the tool table. Changing the diameter in the Feeds & Speeds table also changes it in the Tool. ๏ฎ The surface speed is in feet/min in inch mode or meters/min in metric mode. ๏ฎ The calculated spindle speed is shown for the entered surface speed.
4.1 Tool Table Simulation Tool and Offset Tables The 3500i includes the advanced ability to utilize a second set of the tool and offset tables, which apply only to Simulation mode. This allows a user to create and simulate programs in the background while running another program in the NC Program Run mode, without any interference between the two modes. The Simulation Tool Table and Offset Table are structured and behave the same as the regular NC tables.
4.2 Tool Data 4.2 Tool Data T-Codes, and Tool Activation To activate a tool, program a T-Code followed by the tool number. The tool number corresponds to the row number in the Tool Table. A program tool call example starts with a โTโ, followed by the tool number, e.g. โT1โ. Activating Offsets via the Program In a program, T1 (by itself) calls the Tool Table diameter and length offsets for the specified tool.
4.2 Tool Data Tool-Length Offsets Tool-length offset is the distance from Z0 Machine Home to the tip of the tool at the part Z0 (the surface of the work). Tool-length offsets allow each tool used in the part program to be referenced to the part surface. In an idle state, the CNC does not have a tool-length offset active. Therefore, Tool #0 (T0) is active. When T0 is active, all Z dimensions are in reference to the Z Home position.
4.2 Tool Data ๏ With the tool in the spindle, carefully jog the tool down until it touches the top surface of the work piece. This is referred to as โPart Zeroโ. ๏ Touch the Teach button. The 3500i calculates the tool length offset for the selected tool putting the data to the length column. ๏ Press the Enter button to save the data entered in the field. Diameter Offset in Tool Table When you activate a tool, you automatically activate the length offset and diameter values recorded on the Tool Table.
4.2 Tool Data Tool Radius Compensation When tool compensation is not active, the CNC positions the tool's center on the programmed path. When programming a part profile, the cutting edge must be half a diameter away from the path. Using radius compensation moves the cutting edge half a diameter away from the path. When tool compensation is active, the CNC offsets the tool by half a diameter to position the cutting edge of the tool on the programmed path.
4.2 Tool Data Contouring with radius compensation The tool center moves along the contour at a distance equal to the radius. โRightโ or โleftโ are to be understood as based on the direction of tool movement along the work piece contour as viewed from behind a moving tool. Between two program blocks with different radius compensations, you must program at least one traversing block in the working plane without radius compensation (G40).
4.2 Tool Data Radius compensation: Machining corners ๏ฎ Outside corners: If you program radius compensation, the CNC moves the tool around outside corners on a transitional arc. If necessary, the CNC reduces the feed rate at outside corners to reduce machine stress, for example at very great changes of direction. ๏ฎ Inside corners: The CNC calculates the intersection of the tool center paths at inside corners under radius compensation. From this point it then starts the next contour element.
4.2 Tool Data Ramping into a Compensation Move ๏ฎ Entry moves allow a smooth transition into a contour. Allowing a way to avoid areas you do not want to affect with the tool when entering a contour, Entry Move button (G36). If an entry move without compensation is required, program a tool with โ0โ radius. ๏ฎ Four types of entry moves are available. Refer to Line Tangent Entry Move, Line Perpendicular Entry Move, Arc Tangent Entry Move and Line Arc Tangent Entry Move.
4.2 Tool Data Arc Tangent Entry Move In an arc tangent entry move the tool approaches the contour through an arc and enters tangent to the first move of the contour. The tool feeds from the current position to a calculated point based on the Angle (C) and Radius (R) then feeds through an arc and into the contour tangent to the first move of the contour. To create an arc tangent in the opposite direction, use a negative Radius (R).
4.2 Tool Data Special Code: Temporary Change of Tool Diameter To change the tool radius in order to leave stock for a finish pass, program the โstock-variableโ. The variable assigned for this function is #1030. Example: 120 #1030 = .015 ๏ฎ When the CNC reads the above block, 0.015 is added to the active tool radius. The value in the Tool Table for that tool # is not updated, and tool compensation is affected only until the tool is cancelled. #1030 is temporary.
4.2 Tool Data Tool Compensation Path Path of Tool During Tool Compensation In linear-to-linear or linear-to-circular moves, the position at the end of the startup block Compensation LEFT (G41), or Compensation RIGHT (G42), is perpendicular to the next programmed move in the plane. In either case, the axes moves to a point perpendicular to the next move during the startup block. The length of the XY move that activates compensation must be equal to or greater than the tool radius value.
4.2 Tool Data Intersecting Points You cannot program a plane change during tool compensation. However, a 2-axis move off the currently active plane is allowed. For example: The active plane (compensation in XY). You program an XZ or YZ move. The Z-axis reaches the programmed target as X/Y reaches its compensated target. Helical moves in the active plane are also allowed. Program cancel compensation (G40) alone or with a move in the active plane. The move must be in rapid or feedrate.
4.2 Tool Data General Precautions ๏ฎ When you program tool path instead of part edge, a negative diameter in the Tool Table effectively changes the moves during compensation. ๏ฎ Third axis moves (not in the active plane) are permitted during compensation. ๏ฎ The CNC automatically rounds off the compensated intersection of acute angles of 15 degrees or less. To change this value, program #1031. ๏ฎ It is possible to change the tool diameter currently in use with โstockโ variable #1030.
4.2 Tool Data Fixture Offsets - Tool menu In the Tool menu bar, the Fixture Offset display screen is provided to allow data entry in the display fields to set fixture offsets. ๏ Touch the Fixture Offsets button to open the offsets menu. With the display screen open, data can now be entered, or edited by changing existing information. ๏ ๏ ๏ ๏ ๏ Press the UP or DOWN arrow keys to select a offset line number (the entire row is highlighted).
4.2 Tool Data Lock, or Unlock a Tool In the Tool Table, select the tool to be locked, or unlocked. ๏ Open the column field under โTLโ. Select No to unlock the tool, or Yes to lock the tool. When a toolโs usage limits have been exceeded, the tool is locked. If a replacement tool (โRTโ) has not been specified, โTime1โ or โTime2โ will cause the program to stop. An error message will appear.

Programming: Canned Cycles, sub-programs
7.1 Explaining Basic Cycles 7.1 Explaining Basic Cycles Round/Chamfer Corner Rounding Corner rounding permits the operator to blend the intersection of consecutive moves. To activate corner rounding, the operator keys a radius value (positive) into the CornerRad field of the first move. When the program runs, it blends the endpoint of the first move with the starting point of the second.
7.1 Explaining Basic Cycles Line-to-Arc Corner Rounding ๏ฎ When the first move contains a CornerRad value, the CNC automatically finds the radius center and the tangent points necessary to calculate the tool path. The resulting tool path follows the solid line. If the line move is already tangent to the arc move, the CNC ignores corner rounding.
7.1 Explaining Basic Cycles Rapid Rapid Move Rapid Move initiates rapid traverse. The machine builder sets the actual rapid rate in the Setup Utility. Use Rapid Move to position the tool prior to or after a cut. Do not use Rapid Move to cut a part. ๏ฎ One to four axes can be included on a block with Rapid Move. ๏ฎ X, Y, Z, and U reach the target simultaneously. ๏ฎ Rapid Move is modal, and remains in effect until canceled or overridden.
7.1 Explaining Basic Cycles Rapid Move - Angle and Radius: ๏ฎ Specify the desired end point coordinate using the radius and angle of the movement. Field Code Description Radius R Absolute or incremental distance to the desired destination. (Required) Angle C Polar degree angle of the radius from the start point to the desired destination.

Field Code Description Y Y Absolute position of, or incremental distance to, the desired Y-Axis destination. (Required) Radius R Absolute or incremental distance to the desired destination. (Required) Z Z Absolute position of, or incremental distance to, the desired Z-Axis destination.
7.1 Explaining Basic Cycles Arc Arc Move: An Arc block initiates a feed motion and is used to cut an arc in a part. The 3500i executes arcs in the XY plane by default. For an arc in the XZ or YZ plane, program the plane change before the arc move. After you make all of the required moves in the XZ or YZ plane, return the 3500i to the XY plane. Refer to the section "Plane Selection" for more information on plane selection and arc directions. ๏ฎ One to four axes can be included on a block with an Arc.
7.1 Explaining Basic Cycles Arc Move - Radius and EndPoint: The following is a description of the menu fields. Field Code Description Direction E Specifies a clockwise (CW) or counterclockwise (CCW) arc direction. (Required) Radius R Radius of the arc. Positive value for an included angle less than 180 degrees, negative value for an included angle greater than 180 degrees. (Required) X X Absolute position of, or incremental distance to, the desired X-Axis destination.
7.1 Explaining Basic Cycles Arc Move - Center and EndPoint: ๏ฎ Specify the arc movement using the actual coordinates of the desired end point and the coordinates of the arc center point. Field Code Description Direction E Specifies a clockwise (CW) or counterclockwise (CCW) arc direction. (Required) Xcenter I Absolute position of, or incremental distance to, the desired X-Axis arc center point.
7.1 Explaining Basic Cycles Arc Move - Center and Angle: ๏ฎ Specify the arc movement using the coordinates of the arc center point and the included polar angle. Field Code Description Direction E Specifies a clockwise (CW) or counterclockwise (CCW) arc direction. (Required) Xcenter I Absolute position of, or incremental distance to, the desired X-Axis arc center point. (Required) Ycenter J Absolute position of, or incremental distance to, the desired Y-Axis arc center point.
7.1 Explaining Basic Cycles Using Arc Center and EndPoint to create a circle Since the start point and end point of a circle are the same, you do not need to program an end point to create a circle. Position the tool at the required starting point before you execute the arc move. Omit the end point parameters for X and Y. Conversational example: Arc CCW XCenter 0 YCenter .5 G-code example: G91 G3 I0 J.
7.1 Explaining Basic Cycles Dwell: Dwell (G4) can be used to program a delay between blocks. A Timed Dwell is a timed stop. An Infinite Dwell is a stop that can be canceled only by pressing START. With a dwell activated, the 3500i halts motions on all axes, but other functions (coolant on/off, spindle control) remain active. Do not program any other commands. The time countdown is displayed in the Machine Status Area of the Manual Data Input, and Program Run screens.
7.1 Explaining Basic Cycles Plane Selection Make plane changes prior to circular interpolation. XY is the default plane at power-on. Circular moves and tool diameter compensation are confined to the plane you select (XY, XZ, or YZ). ๏ Select the More Milling button, and then "Plane" from the pop-up menu.
7.1 Explaining Basic Cycles Reference Point Return: The Home command returns the specified axes to their respective permanent reference position. The machine returns directly to its X, Y, Z, and (U) reference point (Machine Home). Axes return from the current position to their reference position at the current feedrate. Alternatively, you can specify a coordinate to rapid to before moving at the feedrate to their reference position. ๏ Select the More Milling button, and then "Home" from the pop-up menu.
7.1 Explaining Basic Cycles Fixture Offset (Work Coordinate System Select): Use the work coordinate system commonly known as fixture offsets to shift Absolute Zero to a preset dimension. Fixture Offset dimensions are referenced to Machine Zero. Fixture Offset cancels Mirroring, Axis Rotation, and Scaling. To activate the Fixture Offset Table from Manual Data Input Mode: ๏ Select the More Milling button, and then "Offset" from the pop-up menu.
7.1 Explaining Basic Cycles Unit (Inch/MM) Use the Unit block to specify and activate the desired unit of measurement in a program. The active Unit is modal, and remains active until overridden. ๏ Select the More Milling button, and then "Unit" from the pop-up menu. ๏ฎ Conversational format: Unit ๏ฎ G-code format: G70 (Inch), or G71 (MM) Field Code Description Unit U The desired modal unit of measurement to activate, Inch or MM.
7.1 Explaining Basic Cycles Absolute Zero Set Absolute Zero is the X0, Y0, Z0 position for absolute dimensions. Refer to chapter 3 "Manual Data Input (MDI)" on page 38 for more information on Absolute positioning. A SetZero block sets the Absolute Zero Reference of one or more axes to a new position. Use SetZero in one of two ways: to reset X0 Y0 Z0 or to preset the current location to the specified coordinates.
7.1 Explaining Basic Cycles Block Form The BlockForm command is used to define a window in relation to the part zero. This is used by the Draw function to present a solid model of the raw stock. Block Form can be placed anywhere within the program and must be accompanied by all of the parameters. ๏ Select the More Milling button, and then "BlockForm" from the pop-up menu.
7.1 Explaining Basic Cycles Temporary Path Tolerance The PathTol command is used to temporarily override the parameter for path tolerance. This should only be used in a program and should be programmed by itself. The value in the system configuration is restored at the end of the program. The typical default is 0.010 mm (0.0004"). This can be useful if the 3500i hesitates between small moves, such as with a 3-D surface output from CAD-CAM.
7.1 Explaining Basic Cycles System Data The SysData command can be used in a program to override system configuration data during the program execution. The new value is only in effect during the program run, and reverts back to the original value after program completion. This is an advanced feature that should be used with extreme caution, and only when absolutely necessary. ๏ Select the More Milling button, and then "SysData" from the pop-up menu.
7.1 Explaining Basic Cycles FeedRate A Feed block sets the feedrate for Line moves, arcs, and cycles that do not contain specifically programmed feed rates. Feed blocks also set the feedrate for modal moves. Add Feed blocks whenever necessary ๏ Select the More Milling button, and then "Feed" from the pop-up menu. ๏ฎ Conversational format: Feed ๏ฎ G-code format: F[n] A Feed block only alters the programmed feedrate, it does not activate the Feed Mode.
7.1 Explaining Basic Cycles Spindle RPM Use the RPM command to designate and activate the desired spindle speed, in Revolutions Per Minute. Programming an RPM does not activate any spindle motion; it only sets the speed at which any subsequent spindle rotation will occur at. ๏ฎ Conversational format: RPM ๏ฎ G-code format: S[n] Field Code Description RPM S The speed of rotation for the spindle to be activated.
7.1 Explaining Basic Cycles Tool Definition and Activation Use the Tool command to define and/or use a tool in the program. On a machine with a fixed bin tool changer, a Tool call will always mount the tool, with no need for the MCode 6. On a machine with a random bin tool changer, the MCode 6 is required in order to mount the tool.
7.1 Explaining Basic Cycles Repeat Blocks The Repeat command allows a series of previously programmed blocks to be repeated one time. Wherever it is used, the repeated blocks will be processed, just as if they were written in the program at that point. For more advanced features including repeating more than once, use the Loop command as an alternative. The Loop command requires the use of a sub-program, whereas the Repeat command does not. Refer to Section 7.
7.1 Explaining Basic Cycles Block Description 11 Y 0.0000 12 DrillOff 13 Offset Fixture# 1 X 3.0000 Y 0.0000 14 Offset Fixture# 1 15 Repeat 7 Thru 12 16 Rapid Z 0.5000 17 EndMain This program will drill four holes. A Fixture Offset is used to relocate X Y zero. When the Repeat Cycle is encountered, it will drill four more holes at the offset location.
7.2 Canned Cycles 7.2 Canned Cycles Canned Cycles A canned cycle is a preset sequence of events initiated by a single block of data. Canned cycles are part of the CNC software and cannot be altered. They simplify the programming of complicated cycles. One block of data can instruct the CNC to perform the necessary moves to drill a hole, or mill a pocket. A canned cycle is in Conversational format, and G-Code.
7.2 Canned Cycles Drilling Cycles Drilling, Tapping, and Boring When you activate a drilling cycle, it executes after each programmed position, until you cancel it. The P entry (return height) is optional, and you do not need to provide it. If you do not specify P, the CNC sets it to R. If P is provided, it must be greater than R, or an alarm is given. The following reminders are for drill cycles: ๏ฎ F feedrate is optional. If it is not given, the current feedrate is used.
7.2 Canned Cycles Counterbore Drill Cycle ๏ฎ Counterbore drill cycle generally used for counterboring. It feeds from the R-plane to Z depth, dwells for specified time, then rapids to the return point. Field Code Description ZDepth Z Absolute hole depth. (Required) StartHgt R Initial Z start point, in rapid. (Required) ReturnHgt P Z return point after hole depth, in rapid. Dwell D Dwell time (in seconds).

7.3 Probing Cycles 7.3 Probing Cycles Tool, and Spindle Probe cycles This section describes operation and an overview of the tool and spindle probe canned cycles available on the 3500i CNC products. The cycles provided perform the most common tool and spindle probing functions. Custom cycles to perform specific functions can be written using the primitive and parametric programming.
7.3 Probing Cycles Tool Probe Cycles Before using your tool probe and tool probe cycles, you must setup the probe following the probe manufacturer's specifications. The tool probe updates the tool registers only. If you are going to use the tool being measured after the probing cycle, you must recall that tool for the new offsets to be active.
7.3 Probing Cycles Tool Probe Calibration Cycle ๏ฎ This is used to set the Z datum for length preset, the effective probe stylus diameter for setting tool diameter registers, and establishes the center of the probe stylus. Calibration must be done at least once before using the tool probe. Once the probe has been calibrated, calibration does not need to be done again unless the probe is moved or a new part is being setup.
7.3 Probing Cycles To calibrate the tool probe: ๏ Jog the calibration standard (the calibration standard should be in the spindle) to the top of your work piece or a common surface where all your tools will be calibrated to, and set its tool-length offset to the top of the work piece or to wherever you would like your Z zero to be. ๏ To calibrate the tool, jog the tip of the calibration standard to the proper spot. ๏ Touch the Teach button.
7.3 Probing Cycles ๏ฎ The Z-axis then does a guarded Z move down 0.1" (2.54 mm) or whatever amount was placed in the E cycle parameter and then moves over toward the probe stylus 0.3" (7.62 mm) or until it touches the probe stylus. If contact is not made with the probe or if contact is made during a guarded move, then an alarm is generated and the canned cycle terminates.
7.3 Probing Cycles Field Code Description Tool# T Tool number. (Required) With only the T cycle parameter present, the canned cycle does not step over half the tool's diameter but comes straight down measuring the tool length and storing it in the tool register.

Code Description DistDown E The incremental distance from the current Z Retract amount to go down along the side of the probe stylus when doing a diameter pick. The maximum E value is 0.55" (13.97 mm) or the tool may crash into the probe or table. If you enter a value larger than 0.55" (13.97 mm), the control issues an error message. If E is not set, the cycle uses a default value of 0.1" (2.54 mm). (Optional) [Default: 0.1"] Ball nose cutters and special cutters that require a move down more than 0.
7.3 Probing Cycles To use the automatic tool preset: Field Code Description OvrSlwFeed S This is the override for the slow feedrate that was set in the machine setup parameter ZFirstPickFeedRate_Slow.

(Optional) OvrRPM R This is the override for the RPM that was set in the machine setup parameter calibAndToolMeasurementRPM.
7.3 Probing Cycles To use the automatic tool preset: ๏ Install all the tools you wish to set, in the tool changer. ๏ Type in: G151 T(tool#) D(tool rough diameter) Q2 If run from the inside of a program, this line needs to be repeated for every tool that you want to set. ๏ Execute that line if you are in Manual, or run the program if you have set all the tools up in a program. ๏ฎ If you have done a single tool in Manual, that tool is now measured and you are ready to measure the next tool.
7.3 Probing Cycles Format: G151 T(tool#) D (tool rough diameter) With T and D cycle parameter only set: ๏ฎ The machine rapids the Z-axis up, picks up the tool designated in the T cycle parameter, and rapids directly over the center of the probe stylus.

(Optional) OvrRPM R This is the override for the RPM that was set in the machine setup parameter calibAndToolMeasurementRPM.
7.3 Probing Cycles From the Manual Data Input Mode with G-code MDI selected and the spindle off, input: ๏ "G153 Tn Dn En" and touch the NC Start button. Where T is the tool number, D is roughly the diameter of the special tool (this should be larger but not more than 0.100" (2.54 mm) larger), and E is the Z-axis move down needed if different then the default 0.100" (2.54mm) so that the largest part of the tool diameter comes in contact with the edge of the probe stylus. For example, G153 T3 D3.5 E.
7.3 Probing Cycles Tool Breakage, Length and Diameter Wear Detection ๏ฎ Checks the tool and gives an alarm if not within tolerance. Length and Diameter Wear - Check the Length and/or Diameter and updates the Length and/or Diameter wear registers up to a user-defined limit. Once the user-defined limit has been reached, the cycle gives an alarm and the program stops. Field Code Description Tool# T Tool number. (Required) The T cycle parameter is the tool number you want checked.
Code Description DistDown E The incremental distance from the current Z Retract amount to go down along the side of the probe stylus when doing a diameter pick.

11.4 Advanced Programming 11.4 Advanced Programming SPEED This section covers S and M code formats. The codes are included in the part program or activated in Manual Data Input Mode. Code Function S (Spindle Speed) Commands spindle speeds (S). Format: Sxxxxx Spindle speed is programmed via S-Code. The RPM range of the machine determines the S-Code range. In determining spindle speeds there also may be gear ranges selected by M-Codes.
11.4 Advanced Programming Control M - Codes Control M-Codes execute or alter certain 3500i functions, such as program end, sub-program call, dry run, etc. These M-Codes are part of the 3500i software. To use them, enter the appropriate M-Code into the program. M-Code Function M0 or M00 Program Stop Mode. Program stops indefinitely. Touch Start to resume. M1 or M01 Optional Program Stop. Optional program stops indefinitely. Touch Start to resume. M2 or M02 End of Program.
11.4 Advanced Programming M-Code Function M106 Dry Run, No Z Axis. M106 in a program or in MDI sets Dry Run (No Z) Mode. All feed moves are executed at a rate set by the builder, and all Z moves are ignored during the dry-run. This enables you to run through a program quickly, without Z-axis movement. M107 disables Dry Run, No Z Axis. NOTE: Making and saving a change to the Setup Utility cancels M106. M107 Dry Run, Off - Cancel M105 and M106. This returns the 3500i to normal operating mode.
11.4 Advanced Programming Programming Non-modal Exact Stop: With the In-Position Mode activated, the 3500i approaches target and performs an in-position check before it executes the next move. The CNC comes to a complete stop at the end of every block. This could cause witness marks to display on the work, but prevents the CNC from rounding off sharp corners. Rapid moves are always performed in In-Position Mode.
11.4 Advanced Programming Setting Stroke Limit: ๏ฎ The software limits feature creates an envelope that limits the tool's range of travel. It is also called the Stored Stroke Limit feature. The X, Y, and Z limits represent the extreme distance the tool can travel in the positive X, Y, and Z directions. The I, J, and K limits represent the extreme distance the tool can travel in the negative X, Y, and Z directions. Software limits are referenced to Absolute Machine Zero.
11.4 Advanced Programming Modifiers Use modifiers to alter the way the 3500i interprets a word address. For example, a single value in an Inch Mode program may be forced to Metric Mode, without programming G71. Or, arc center values (I, J, or K) may be forced to an absolute value. ๏ฎ The address and modifier must be accompanied by an ampersand (&). Place the ampersand (&) between the address word to be modified and the modifier.
11.4 Advanced Programming Tool Offset Modification You can modify a tool diameter or length offset in the program without using the Tool Page. This is useful when rough-milling a profile where cutter diameter compensation requires different diameter definitions for the same tool to step the width of the cut. Tool modification can be either temporary or permanent. To make it temporary, choose not to update the Tool Page. To make it permanent, choose to update the Tool Page. Temporary Format: T1 D.5500 L-1.
11.4 Advanced Programming Tool Modification Programming Example: This program mills the square shape four times. The 3500i executes the first pass using the tool diameter entered in the Tool Page. Each subsequent pass uses a different, "modified" tool diameter, as programmed in Blocks 8, 10, and 12. T, D, L, and H are the only word addresses allowed on the block. Block # Block N1 O41 * TOOL-MOD.G N2 G90 G70 G0 G17 N3 T0 N4 Z0 N5 X0 Y0 N6 T1 * .8000 DIA. N7 M98 P1 N8 T1 D.
11.4 Advanced Programming Block # Block N16 M2 N17 N18 O1 * SUBPGM-1 N19 G1 Z-.25 F10 20 G41 Y1 N21 X-1 N22 Y-1 N23 X1 N24 Y1 N25 X0 N26 G40Y0 N27 M99 The main program calls the sub-program that contains the compensation on/off commands between each tool modification. When tool modifiers are activated, the 3500i still applies any wear offset entered in the Tool Page.
11.4 Advanced Programming Expressions and Functions You can program some values as expressions. Parentheses enclose expressions. The 3500i displays an error message if the expression is incorrectly entered. Expressions follow the standard mathematics order of operations (multiplication, division, addition and subtraction). ๏ฎ An expression must contain an operator or use a function. Operators and Functions Ref.
11.4 Advanced Programming Ref. Expression Function s) atan Arctangent t) abs Absolute value u) sqrt Square root v) ln Natural logarithm w) log Logarithm x) exp Exponential y) trun Truncate z) !+-# Unary logical not, positive, negative, indirection Function names are case insensitive.
11.4 Advanced Programming Examples Ref. Example a) G01 X(#100 + #101). All calculations must be enclosed in parentheses. This defines an expression. b) G00 Y&A(#102 * #103) LOOP (5 / 2 / .01) Example of multiplication, division, and modification. c) G01 X(3 + 2) #100 = (#122 - #105). Addition and Subtraction. d) IF (#101 > 0) THEN . Greater than (>), less than (<). e) IF (#144 = #143) GOTO ... Equal to, not equal to (!=) f) TOMM (n); convert n to mm. If n's type is inch, TOMM (n) = n * 25.
11.4 Advanced Programming Ref. Example n) SIN (n) gives the sine of (n). (n) is assumed to be in degrees. G01 X(cos(15)) Y(sin(15)) moves along the hypotenuse of a 15-degree angle with a hypotenuse of 1. o) COS (n) gives the cosine of (n). p) TAN (n) gives the tangent of (n). q) ASIN (n) gives the arcsine of (n). r) ACOS (n) gives the arccosine of (n). s) ATAN (n) gives the arc tangent of (n). t) ABS (n) gives the absolute value of (n). u) SQRT (n) gives the square root of (n).
11.4 Advanced Programming System Variables Certain variables are set aside as 3500i system variables. Some may be useful for you to know when programming macros. The system variables range from #1000 to #1099. Most of these variables are "read only". You cannot write information to them. There are a few exceptions to this rule.
11.4 Advanced Programming User Variables Certain variables are set aside for the programmer to use. These may be useful when programming macros. You can read from or write to these variables. They are divided into four categories: ๏ฎ Local variables: #1 to #99:These variable numbers can be used only within the body of a sub-program (or macro). The 3500i generates an error message if you program these variables in the main program. Values do not hold from one sub-program to another.
11.4 Advanced Programming Variable Programming (Parametric Programming) Variable, or parametric, programming enables you to create macros to generate geometric shapes that are not already available in a canned cycle. Conditional loops, jumps, and GOTO commands can be used to control program execution. Block Skip Any block preceded by a slash (/) code is omitted if the corresponding block skip 'switch' is set "ON" in the program, previous to the (/) code.
11.4 Advanced Programming Select Block Skip The 3500i control has nine (9) optional block skip 'switches'. The (/) code followed by a number 1 through 9 activates the corresponding switch. Example: N11 #1002 = 1 *Note: 0=OFF, 1=ON N12 G81 Z- .5 R.1 F12 P.1 N13 X1 Y1 N14 X2 /2N15 X3 N16 X5 N17 G80 ๏ฎ In this example, the hole at N15 is skipped. If N11 read: N11#1002 = 0 Then N15 would be executed. ๏ฎ #1001 through #1009 are reserved for optional block skip use.
11.4 Advanced Programming Parameters and Variable Registers A macro is a series of instructions designed to achieve a specific result for a given set of constraints. For example, a rectangular pocket of any size always has four sides, four corner radii and a depth. Therefore, you can cut many pockets of different sizes using a similar tool path with longer or shorter moves for the tool path.
11.4 Advanced Programming Setting and Direct Transfer Variables When using parametric programming with axis addresses and expressions (including unary minus), the complete expression needs to be in parenthesis. For example, X(-#151) is correct. X-#151 or X-(#151) is not correct. ๏ฎ Variables are loaded or set when they display on the left side of an equation. (That is, the left side of the equal sign). Example 1: N200 #100 = 5.56 ๏ฎ Variable #100 contains number 5.560000 until changed.
11.4 Advanced Programming Indirect Transfer: You can indirectly transfer variables to a depth of four levels by introducing extra hatch marks (#) before the variable number. In an indirect transfer, a value is transferred to one variable via another. Example 1: N201 G90 G17 G71 G0 N202 #101 = 51.456 N203 #102 = 101 N204 X##102 ๏ฎ At Block N204, the X-axis moves to 51.456. Example 1 shows single indirection. The contents of variable #101 are used by variable #102.
11.4 Advanced Programming Example 2 contains two levels of indirection (N219) and shows how the contents from multiple variables can be assigned to a command or expression. ๏ฎ At Block N215, variable #119 is set to constant 100. ๏ฎ At Block N217 one is added to the contents of variable #119. ๏ฎ At Block N218 variable #120 is set to constant 119. ๏ฎ Block N219 moves the X-axis to the position contained in variable #120 via two levels of indirection. The first level is the content of variable #119.
11.4 Advanced Programming Variable Programming Examples This program uses common variables in the range of #50 to #149. The program mills a pocket with a three-degree draft angle on the sidewalls. The dimensions at the bottom of the pocket are: 15.5730 (X axis) x 13.8850 (Y axis). The pocket is 1.0000 in. deep. The tool begins at the upper-left corner of the pocket and at full depth. Part Zero is set in the center of the pocket. Example 1: O 28 * 3-Deg.
11.4 Advanced Programming X0 Y0 M2 O100 LOOP((1/#103)+1); * SET LOOP NUMBER (1 IN. DP / .02 STEP) + 1 G91 * SET INCREMENTAL MODAL G1 Y(-#102); * MILL L.H. SIDE X#101; * MILL BOTTOM SIDE Y#102; * MILL R.H.

11.4 Advanced Programming User Macros (G65, G66, G67) Use G66 when you want to use a modal macro sub-program. These groups of instructions can be special canned cycles made up by the user to simplify the programming of the particular part, or master programs for similar part families, programmed with variables rather than fixed dimensions. Macros can contain automatic measuring sequences for sensors, such as a probe, for feedback to the 3500i. Format # Function G65 Pn Ln Non-modal macro call.
11.4 Advanced Programming Macro Body Structure The macro body is defined in the same way as a sub-program. Format: Oxxx O identifies it as a macro. xxx is the label number. Example 1: N200 O 201 N210 ----- Terminate the macro with an M99 code. Use local variables within the body of a macro or sub-program only. You cannot use them to transfer data to other macros or sub-programs.
11.4 Advanced Programming Setting and Passing Parameters ๏ฎ You can set parameters for a macro before the sub-program call (M98 Pn). Refer to Example 1. Blocks 10 to 12 define variable values for the sub-program called in Block 13. Example 1: N10 #151 = 2 N11 #151 = 3 N12 #151 = 3.4 N13 M98 P1 N14 ----- ๏ฎ It may be more convenient to use macro call G65 Pn or G66 Pn to pass variables to the sub-program by letter address. This is how a canned cycle operates. Refer to Example 2.
11.4 Advanced Programming G65 Macro Programming, Main The following is an example of a simple macro program. In this example, the macro is a "window milling" cycle designed to mill a square or rectangular window through a part. Block # Block N1 O99 * WINDOW-MACRO-CALL N2 G90 G70 G0 G17 N3 T0 N4 Z0 N5 X0 Y0 N6 T1 * .5000 DIA. N7 G90 G0 X1 Y1 N8 Z.1 N9 F40 N10 G65 P3 X4 Y4 Z-.55 N11 G90 G0 Z.
11.4 Advanced Programming G65 Macro Programming, Macro (sub-program) This macro can mill any size window (L x W), at any Z depth. To change the pocket size, change the parameters on Block 10 (X,Y,Z). The 3500i executes the macro only once, at the current position (G65 is not modal).
11.4 Advanced Programming G66/G67 Macro Programming This example is a modal macro program to mill slots in a plate at various locations. In contrast to the G65 (single-call macro) in Example 1, G66 (modal macro call) applies the macro to all subsequent moves, until canceled by G67. Program G67 after the last slot location. Block # Block N1 O101 * SLOTCALL.G N2 G90 G70 G0 G17 N3 T0 Z0 N4 X0 Y0 N5 T1 D.25 L 1 F30 N6 G66 P1255 X5 Y1 Z .
11.4 Advanced Programming SLOTMAC.G Program In the following example, Blocks 1260 through 1400 are comment blocks that regard the macro's structure and concept. Block # Block N1255 O1255 * SLOTMAC.G N1260 N1270 * EXAMPLE: G65 P1255 X 3 Y1 Z .

11.4 Advanced Programming Macro Programming (Hole Milling Macro) This example machines a CW or CCW hole. A move is made to the hole center and to the required Z depth before calling the macro. After the macro is completed, the Z-axis moves to the clearance plane. The macro contains tangential entry to and exit from the hole surface. It uses error checking and messages. When the macro is finished, machine parameters return to their previous status. String variables (e.g.
11.4 Advanced Programming Example: G90 G70 G0 G17 T0 Z0 X0 Y0 T1 F30 X1.5 Y0 * MOVE TO HOLE CENTER Z.1 G1 Z-.5 * MOVE Z TO DEPTH G65 P76 D2.0 S.010 J35 K20 G0 Z.1 * RAISE Z TO CLEARANCE PLANE TO Z0 X0 Y0 M2 O76 ** HOLE MILLING MACRO. * * D#7 = HOLE DIAMETER (+=CCW,-=CW), J#5 = ROUGH FEEDRATE, * S#19 = FINISH STOCK AMOUNT, K#6 = FINISH FEEDRATE. * #1020 = TOOL DIAMETER.

11.4 Advanced Programming Probe Move (G31) G31 is to be issued with an associated axis move (i.e. G31 X10). When the G31 is executed, it moves at current feedrate selected for G1 until the touch probe selected is deflected. At this point, the move is stopped, and the position where the probe touched the part is read and passed to system variables (#1060 to #1063 for X to U).
11.4 Advanced Programming Conditional Statements This subsection discusses the conditional statements IF, THEN, ELSE, GOTO and WHILE. IF - THEN - ENDIF N300 IF (expression) THEN N310 ------------- --- --- --- -N360 ENDIF N370 -----------If the expression in N300 is true, the program continues at N310. If the expression is false, the program continues at N370. In place of an expression, you can use a variable that while not zero is treated as a true expression. (Zero equals false.
11.4 Advanced Programming If the expression is true, the program continues at N410, then to N440, where a jump is made to N480. If the expression is false, the 3500i skips Blocks N410 to N440 and executes Blocks N450 to N470. In place of an expression, you can use a variable that while not zero is treated as a true expression. (Zero equals false. Any other value equals true).
11.4 Advanced Programming In place of an expression, you can use a variable that while not zero is treated as a true expression. (Zero equals false. Any other value equals true). DO - END N620 DO nnnn N630 ------------- --- --- --- -N650 IF ( expression ) GOTO 1111 N660 -----------N670 END nnnn DO END sets the program into an infinite loop that can only be ended by programming a GOTO (1111) command to another block. DO and END must be paired with labels (nnnn).
11.4 Advanced Programming LOOP instructs the control to execute the following blocks (N685) until it reaches an END command. The sequence is repeated nnnn times. The number of loops can be a variable assignment (LOOP #121). GOTO N698 GOTO nnnn N699 -----------GOTO is an instruction to continue program execution at the block specified (nnnn). You should not require this instruction in a user macro. It is intended for use in conjunction with the block skip symbol (\), as shown in the example.
11.4 Advanced Programming Logical and Comparative Terms LOGICAL TERMS All logical operations can be carried out using the following command characters or combinations of characters. Statement Symbol True/false Table OR ยฆ 0-0= False 0-1 = True 1-0 = True 1-1 = True EXCLUSIVE OR ^ 0-0= False 0-1= True 1-0= True 1-1 = False AND & 0-0= False 0-1= False 1-0= False True COMPARATIVE TERMS You can compare variables with variables and variables with constants using equality and inequality operators.
11.4 Advanced Programming INEQUALITY OPERATORS NOT N760 WHILE (#135 != #137) DO 10 N770 ------------- --- -N790 END 10 The exclamation mark (!) symbolizes NOT. Therefore, Block N760 instructs the 3500i to continue the loop to N790 while the contents of variables #135 and #137 are not equal (condition true). When the contents of the variables become equal the expression is false and the loop terminates. GREATER THAN N800 IF (#122 > #134) GOTO 830 N810 -----------The symbol (>) symbolizes GREATER THAN.
11.4 Advanced Programming File Inclusion File inclusion is a function that allows a sub-program that is not actually part of the program to be called from the main program, or from another sub-program in the program. In this way, a tool change sub-program or a macro can be stored in the directory, and called from any other program that has the proper "file inclusion" code, which allows the execution of the external sub-program.
11.4 Advanced Programming Example 2: Block # Block N1 O23 * TEST.G N2 M98 P9 N3 T1 * 1.0000 MILL N4 G0 X-.6 Y.6 N5 Z.1 N6 - N7 - N33 M98 P9 N34 T2 N35 * .368 DRILL N36 N50 M98 P9 N51 M30 O23 N52 ["TOOLCHNG.
11.4 Advanced Programming In Example 2, a program named TOOLCHNG.G can be called from the main program (or from an existing sub-program). It is made possible by line N52. The program inclusion function is programmed on N52. In this way, the same sub-program can be used in many programs, but you do not need to type it into each program. Each program must, contain the proper "program inclusion" block.
11.5 Four Axis Programming 11.5 Four Axis Programming Axis Type The machine builder sets up the fourth-axis as a linear or rotary axis. The three basic axes are X, Y, and Z. The additional axis is designated as โUโ on the 3500i console. The following formats are for programming the linear or rotary fourth axis: Linear: Program as Feed Mode (G1) or Rapid (G0) moves. Only rapid and linear feed moves can be programmed.
11.5 Four Axis Programming Rotary Axis Programming Conventions ๏ฎ A rotary axis (typically U) programs differently based on the setting of the (Axes->PhysicalAxis->U->CfgRollOver>Shortest Distance) parameter, which is determined by the builder. The default for this parameter is off; in which case, the U-axis behaves like a linear axis. If set to on, the behavior of the rotary axis (U) is described below.
11.5 Four Axis Programming Example 1: Drill ๏ Mount the fourth axis as described above. Mount a part 6โ wide and 8โ long on the face of the rotary table. Shortest Distance is set to off. ๏ Drill (10) ten 0.375โ holes 36ยฐ apart, 1โ deep, 0.75โ in from the end of the cylinder. Then, starting at X-2 U0, drill a spiral series of holes 36ยฐ and X-0.500โ apart each. Set X0 at the right end, Y0 at the cylinder's center line, U0 at a pre-milled keyway on the cylinder.
11.5 Four Axis Programming Example 2: Mill ๏ Mount the fourth axis as described above. Mount a part 3โ in diameter and 5โ long on the face of the rotary table. The part has a 0.25โ radius turned on the end. Shortest Distance is set to off. ๏ Assume that a series of six 0.25โ wide grooves must be milled 60ยฐ apart, 0.25โ deep at the start, tapering up to 0.125โ deep and rotating 15ยฐ at the far end. The groove must follow the end contour of the part (radius).
11.5 Four Axis Programming Example 3: Mill ๏ Mount a fourth axis as described above. Mount a part 4โ in diameter and 8โ long on the face of the rotary table. Support the part on the X+ end by a live center. The part has a 0.25โ, 45ยฐ chamfer on one end. Shortest Distance is set to on. This prevents the need to unwind the U-axis, saving operation time. ๏ Table 15-3 shows a thread-milling example. Assume that a 4-8 UN 2A thread must be milled from the right end, 6โ long.
