Follow this procedure to get final values for the MRZP settings. You can also use this procedure to check your current setting values against new readings, to make sure the current values are correct.

If you want to use this procedure to check your current setting values, make sure that the setting values you start with are close to correct to begin with. Values of zero generate an alarm. If the settings are too far off, the probe will not contact the gauge ball when it rotates positions during the cycle. The MRZP rough set process establishes appropriate starting values, so if you are unsure of the current values, you should do the MRZP rough set process first.

To do this procedure, you need a gauge ball with a magnetic base.

  1. Place the gauge ball on the table.
    important: So that the gauge ball post does not interfere with the probe, position the ball post at an angle of approximately 45 degrees to the X Axis.

  2. Load or command the work probe into the spindle.
  3. Position the work probe above the tooling ball.
  4. Press EDIT.
  5. Select the VPS tab, then use the RIGHT cursor arrow key to select Probing, Calibration, MRZP Calibration, and then MRZP Finish Set.
  6. Highlight variable B, and then type the gauge ball diameter. Press ENTER.
  7. Press CYCLE START to immediately run the probe program in MDI, or press F4 to choose to output the probing program to the clipboard or MDI to run later.
  8. When the probing program runs, it automatically places values in macro variables #10121, #10122, and #10123. These variables show the machine rotary zero point axis travel distance from the home position in the X, Y, and Z Axes. Record the values.
    note: Press CURRENT COMMANDS and select the Macro Vars tab to view the variables. When the cursor is in the variable list, you can type a macro variable number and press the DOWN cursor arrow key to jump to that variable.
  9. Enter the values from macro variables #10121, #10122, and #10123 into Settings 255, 256, and 257, respectively.
