MLTmanual.QXD 2/12/02 4:10 PM Page 6 I N S TA L L ATION Overview This manual will guide you through the installation, setup, and operation of the MICRO-LINE system. Use it to get your system up and running “out of the box” and as a quick reference guide for your day-to-day operations. We recommend installing the scales first, according to the instructions included with your system. After the scales are in place, install the readout and then finish setting up the system.
PAGE 5
MLTmanual.QXD 2/12/02 4:10 PM Page 7 INSTALLATION Preparation Packing List Before you begin the installation procedure, check that you have received all of the components for your system: • • • Readout & installation instructions Mounting arm MICRO-LINE scales - Cable mounting hardware - Scale mounting hardware • Warranty card If a component is missing, contact your MICRO-LINE distributor for replacement parts.
PAGE 6
MLTmanual.QXD 2/12/02 4:10 PM Page 10 INSTALLATION Installing the Scales Install the linear encoders according to installation instructions found within your Micro-Line system manual. These general installation instructions are found on page 33. Read these instructions completely even though bracket kit instructions supersede them. Installing the Readout Follow the readout installation instructions that are included with your mounting arm bracket kit.
PAGE 7
MLTmanual.QXD 2/12/02 4:10 PM Page 11 INSTALLATION Power Up Press the switch on the back of the readout to power up the system. A series of tests will check that the display, keypad, and memory are all working properly. If a problem is detected, an error code will appear on the screen. (Error messages and solutions are listed on pgs. 25 - 26.) It is important to note that the E1 message will appear every time you power up your system and does not indicate a problem.
PAGE 8
MLTmanual.QXD 2/12/02 4:10 PM Page 14 SETUP Parameter Setup There are 3 to 4 parameters that you can define on your system: • Display resolution (diS) • Linear error compensation (LEC) • Scale count directions (Ct dir) • Input 3 ON/OFF for international units Establish each setting the first time you power up the system. You can change the parameters later by returning to Setup and then using the ENTER key to scroll to the appropriate category.
PAGE 9
MLTmanual.QXD 2/12/02 4:10 PM Page 15 SETUP Display Resolution The display resolution determines how detailed each scale’s position will be displayed on the readout. Use the setting that best suits each job. To change the display resolution: • Press the SETUP key. (“diS” will show on the display.) • Press the X or Z key for the display you want to change. For 10µm scales, the display resolution will toggle between 0.01 mm (0.0005”) and 0.02 mm (0.001”). For 5µm scales, it will toggle between 0.
PAGE 10
MLTmanual.QXD 2/12/02 4:10 PM Page 18 SETUP Linear Error Compensation With MICRO-LINE, you can compensate for machine tool wear. If you know the linear error compensation (LEC) value in parts-per-million (PPM), you can enter it directly. If you don’t know the LEC, use the formula on the next page to determine the value for each axis. To change the linear error compensation: • Move to the “Linear Error Compensation” display in the Setup mode. (Press SETUP and then the ENTER key until “LEC” appears).
PAGE 11
MLTmanual.QXD 2/12/02 4:10 PM Page 19 SETUP How to Determine the Linear Error Compensation Follow this procedure for each axis: • In the DRO mode. • Place a standard of known length on the machine. Make sure it’s parallel with the axis being measured. • Put the readout in the absolute display mode (ABS/INCR key). • Using an indicator, locate one end of the standard. • Press the ZERO key twice for the axis you are measuring. “0” should appear on the display.
PAGE 12
MLTmanual.QXD 2/12/02 4:10 PM Page 22 SETUP Count Direction Use the count direction setting to define the positive counting direction for each scale. The direction will be displayed as a “1” or a “2” (the numbers are not assigned to a particular direction). You only need to change the count direction if the scale is counting in the negative direction during a positive move, or vice versa. Refer to Conventions (pg. 31) for more guidelines.
PAGE 13
MLTmanual.QXD 2/12/02 4:10 PM Page 23 SETUP International Units Only Input 3 ON/OFF This parameter allows you to activate the third input. When this input is enabled, Inputs 2 and 3 will be coupled on the Z-axis (both scales will count on the Z-axis). When Input 3 is enabled, additional parameters will need to be setup. Refer to the procedures on pages 7-9 for setting up the Linear Error Compensation and Count Direction Setup functions.
PAGE 14
MLTmanual.QXD 2/12/02 4:10 PM Page 26 SETUP Testing the Scales Follow these steps to confirm that your scales have been installed properly. This test will confirm the scale’s electrical operation, and will also check the installation integrity. • Locate a magnetic base on the machine and set the dial indicator on the scale’s reading head casting. Zero the readout and the indicator. • Move the axis through the full travel and return the dial to “0.” The readout should also read 0 (±.
PAGE 15
MLTmanual.QXD 2/12/02 4:10 PM Page 27 OPERATION Radius and Diameter Pressing the RAD/DIA key lets you view the X-axis dimension either as a radius or as a diameter. Display resolution is affected by the RAD/DIA key.
PAGE 16
MLTmanual.QXD 2/12/02 4:10 PM Page 30 OPERATION Setting the Datum (Absolute Zero) MICRO-LINE allows you to measure both absolute and incremental dimensions. A dimension measured from the point you define as the datum is an absolute dimension. A dimension measured from any other point on your print is an incremental dimension. Datum, also known as absolute zero or workpiece zero, is the reference point from which MICRO-LINE will base all of your part’s coordinates.
PAGE 17
MLTmanual.QXD 2/12/02 4:10 PM Page 31 OPERATION If you’re using 5µm (0.0002”) scales (international units only), MICRO-LINE can recall your last datum position each time you power up the system (refer to pg. 32 for the proper procedure). To set the datum at the tool’s current position: • Position the workpiece in the chuck. Move the tool until it is positioned at the location where you would like to establish the datum. • Using the ABS/INCR key, select the absolute (ABS) mode.
PAGE 18
MLTmanual.QXD 2/12/02 4:10 PM Page 34 OPERATION Example: Setting Up Your Job 1. Place your workpiece into the chuck. 2. Make a face cut and clear the work piece by backing the tool off in the X-axis only. Do not move the Zaxis. (Fig. 2) 2 3. Zero the Z-axis by pressing the Zzero key twice. (Fig. 3) 4. Make a skim cut on the diameter of the workpiece and clear the workpiece by backing the tool away in the Z-axis. Do not move the Xaxis. (Fig. 4) 3 5. Measure the diameter of the workpiece. (Fig. 5) 6.
PAGE 19
MLTmanual.QXD 2/12/02 4:10 PM Page 35 OPERATION Incremental Dimensions As we described earlier, incremental dimensions are measured from the current tool position. If your tool is currently at 2” and you want to move an additional 3.125”, you would select the incremental mode, zero out the axis, and move the axis until the display reads 3.125. An example of how to measure using incremental dimensions is shown on page 17.
PAGE 20
MLTmanual.QXD 2/12/02 4:10 PM Page 38 OPERATION Example: Incremental Dimensions Let’s say that your print looks like this: Using Incremental Zero In order to cut a groove to a depth of 0.120” from the 1” radius, it is necessary to establish a zero at 1”. This can be done using the incremental mode without changing the Datum. Follow these steps: 1. Move the tool until the readout display shows that the X-axis = 1.0000” and the Z-axis = 2.0000” in the absolute mode. 2.
PAGE 21
MLTmanual.QXD 2/12/02 4:10 PM Page 39 OPERATION Tool Offset The MICRO-LINE can store the dimensional offset of an additional tool. This allows you to use two tools without having to reestablish zero as you change between them. In order for this feature to work, the tools must be able to repeat their location when they are changed (Repeatable tooling). To use this feature you must first select the tool number (either 0 or 1). 1. 2. 3. 4. Place your first tool in the tool holder. Press the TOOL USE key.
PAGE 22
MLTmanual.QXD 2/12/02 4:10 PM Page 42 OPERATION 11. Move the tool so that it touches a face of known length. 12. Press the TOOL DEF key and press the Z key. 13. Enter 0 if the tool is at Datum or enter the distance the tool is from Datum by using the ± key if the tool is in the negative direction. Press ENTER. Note: Both tools are now set. To switch between them, change the tool on your lathe, then press the TOOL USE key, and select the appropriate tool number.

DRO Mode The MICRO-LINE system is considered to be in the DRO (digital readout) mode when the X-axis and Z-axis positions are displayed. Count Direction MICRO-LINE uses positive and negative numbers to display the position of the tool along each axis.
PAGE 35
MLTmanual.QXD 2/12/02 4:10 PM Page 21 REFERENCE Recalling the Last Datum Setting For International Units If you’re using 5µm MICRO-LINE scales, MICRO-LINE can retrieve your last datum setting when you power up your system. This feature is especially useful when you have to shut down the system in the middle of a job, or if a power interruption occurs. When power is restored, MICRO-LINE will use Position-TracTM technology to read the scales’ reference marks and recall the datum within seconds.
