Setting Up The Unit Language Setup This setting enables the user to choose the language that is required to be displayed in the DP700 display.
Setting Up The Unit Direction of Travel Setup You use the direction setting to match the DP700 to the actual direction of travel of any axis. There are two settings for each axis Press the axis select key ---i and i--- next to the ‘X’, ‘Y’ or ‘Z’ axis to cycle through options Example If the current setting is the setting to ---i i--- and the travel is positive from right to left, changing will reverse the direction to measure positive from left to right.
Setting Up The Unit Error Compensation Your digital readout (DRO) system helps you to improve productivity. It decreases the number of scrapped parts, as you no longer have to be concerned about making mistakes related to counting the revolutions on the dials. Your DRO system also helps to eliminate some errors related to ballscrew backlash. Your DRO system will operate to its published accuracy, provided all components are in working order and properly installed. Field calibration is not necessary.
Setting Up The Unit Types of Machine Error There are many types of machine error, including pitch, roll, yaw, flatness, straightness, and Abbé error. The diagrams below demonstrate these errors.
Setting Up The Unit Linear Error Compensation Setup This setting allows you to setup compensation factors for linear errors. There are two methods of entering compensation values Teach mode and Program mode. Teach Mode Teach mode is an easier way of calculating linear errors by using the DP700 to automatically calculate the error, by comparing the actual measurement and the physical movement. The procedure to do this is shown below.
Setting Up The Unit Segmented Error Compensation The scale travel is broken down into as many as 200 user-defined segments, each with their own correction factor, measured against a high-accuracy standard. The following parameters need to be identified: Starting point - zero Error 5 1 4 2 6 0 Travel 3 Correction points Reference point Each Correction Point is measured with respect to the Starting Point - zero - which is usually set close to one end of the scale.
Setting Up The Unit Segmented Error Compensation Setup (continued) Note. When using Segmented error, each time you turn on the DP700 you need to move to the machine reference point. The DP700 will prompt you for this on power up, see below. reset segments reset? Note.
Setting Up The Unit Functions Setup This setting enables the user to choose the functions that are required to be used with the DP700. Functions that are switched off will not show in the function menu or message display.
Setting Up The Unit Sleep Setup This setting enables the user to define an automatic sleep mode after a period of time. The user either leaves the default setting at 0 which deactivates the sleep mode, or inputs a value (in whole minutes) for when the sleep mode is initiated after no operation of the DP700. To exit sleep mode, simply move an axis or press any key.
Standard Functions This chapter details the standard functions of the DP700. Absolute / Incremental Press to toggle between absolute and incremental mode Absolute (abs) mode has been selected The DP700 has a dedicated key to switch the positional displays between absolute (abs) and incremental (inc) measurements. The current display mode is indicated by a red LED either above or below the key as shown right.
Standard Functions Zero and Preset an axis Press to toggle between ‘set’ and ‘zero’ mode The DP700 has a dedicated key to switch the operation of the axis selection key between zero mode and set mode. The currently selected mode is indicated by an LED either above or below the key as shown right. Zero mode has been selected Set mode has been selected Using Set Mode With set mode selected, this enables the select axis keys to prompt a numeric entry into the desired axis.
Standard Functions Half Function / Centre Find Press to initiate the half function. The DP700 has a dedicated key to half the value in any axis. This is done by initiating the half mode and selecting the required axis. This can be seen in the example on the right. 100.000 Press the axis select key relevant to the axis 50.000 Digifind / Reference Function The DP700 comes equipped with Digifind, a feature unique to Newall digital readout products.
Standard Functions Sub Datums / Memory The DP700 can store up to 200 SDM (Sub-Datum) positions, or machining steps into the memory. Using SDM allows the operator to work to zero by calling up stored dimensions, instead of "working up" to drawing dimensions. This eliminates the need to constantly refer to the drawing, and reduces the possibility of scrapping parts due to misread dimensions. It also speeds up positioning because the operator works to zero.
Standard Functions RS232 (Data Logging) / Data Acquisition The DP700 DRO can offer basic serial communications via a dedicated hardware RS232 compatible port, this is used for data logging purposes. RS232 Connections You connect the RS232 to the DP700 via a 15-pin D-type connector at the rear of the display. The required connection details to make this possible are shown below.
Standard Functions RS232 Setup How to navigate to RS232 setup. Until message display shows , Message display now shows off LOg output funcs LOG Note: Relates to output options of the RS232 Communications to scroll through output options. (Off, ENT, Periodic) Once selected Note: Ent, is for operating the RS232 on request. The enter key is pressed when the output is required. Periodic, is for operating the RS232 at set intervals. The interval is defined in the RS232 setup.
Standard Functions RS232 Output Data Format The output data from the RS232 is as follows: The current axis data for the axes available on the system are transmitted. For two axes systems, only two axes of data will be transmitted. The data packet structure of 12 characters is defined as follows: A : 0 Axis ID Separator 0 0 0 0 0 0 0 0 CR LF Line feed character 9 characters for position Carriage return character The Axis ID is the representation of the axis at the time of printing.
Mill Functions This chapter details the Mill functions of the DP700. The mill functions use the plane setting from setup. PCD / Bolt Hole Circle The DP700 calculates positions for a series of equally spaced holes around the circumference of a circle. The message display prompts the user for various parameters it needs to do the calculations. Once the DP700 completes the calculations, the axis displays show the distance to each hole. The operator works to Zero for each hole location. See example below.
Mill Functions Line Hole The DP700 calculates positions for a series of equally spaced holes on a line. The message display prompts the user for various parameters it needs to do the calculations. Once the DP700 completes the calculations, the axis displays show the distance to each hole. The operator works to zero for each hole location. See example below. How to navigate to line hole function.
Mill Functions Arc Contouring The DP700 calculates positions for rough machining an arc or radius. The message display prompts the user for various parameters it needs to do the calculations. Once the DP700 completes the calculations, the axis displays show the co-ordinates, which are point to point positions along the arc. The operator works to zero for each hole location. See example below. How to navigate to arc contouring function.
Mill Functions Polar Co-ordinates The Polar co-ordinate function enables the operator to convert the displayed data from the conventional cartesian co-ordinates (X,Y) to polar (length + angle) co-ordinates for any plane XY,XZ or YZ. See example below. How to navigate to Polar co-ordinate function. Until message display shows a 116.56 r 22.361 Note: Figures in box will vary depending on current position. Example Cartesian Co-ordinates -10.000 20.000 Polar Co-ordinates a 116.56 r 22.
Lathe Functions This chapter details the Lathe functions of the DP700. Tool Offsets The Tool Offset function allows the operator to enter and store offsets for a range of tools.This enables the operator to change tools without resetting absolute zero or datum. Using tool offsets ensures that diameter and length measurements will remain consistent after tool changes.This speeds up tool changes and increases productivity as it eliminates the need for the operator to stop and manually measure the diameter.
Lathe Functions Program Mode Display will show tools program tools teach Display will now show 0.000 0.000 set tool tool 01 Note: to select different tools Take a skim cut if X axis is selected, or take a face cut if Z axis is selected Note: Tool must not be moved off the part after taking the cut. User needs to enter the difference between measured diameter and readout value Repeat the above process for all the tools required.
Lathe Functions This function only applies to units with software version 1.1.0 and above. Multiple Tool Datums The Multiple Tool Datum function offers several advantages when compared to the standard Tool Offset function. - Multiple Datums - Each tool has its own independent datum (tool datum) - Quick Tool Edits - Changes can be made on the fly, with live position display Application Several tools are required for work on a particular piece.
Lathe Functions Taper Function The taper function shows the angular displacement of the displayed (X,Z) position. How to navigate to Taper function. Until message display shows taper 90.00000 Note: Figures in box will vary depending on current position. Example Touch tool to one end of the taper and zero both axes, then touch the tool on the other end of the taper. Message window will now display the taper. 10.000 50.000 taper 11.30993 10.00mm 50.
