Next Generation Control - Probe Calibration (VPS) - Introduction

This procedure tells you how to do these tasks for the tool probe and the work probe:
  • Make sure the probes operate correctly.
  • Calibrate the probes.

Next Generation Control - Work and Tool Probe - Test

This procedure tells you how to test the spindle-mounted work probe and the table-mounted tool probe.

Step 1

Do this step to make sure the work probe operates correctly:

Put the work probe in the spindle.

Operate this code in MDI mode:

M59 P3;

Use your finger to push on the tip on the work probe. When you push on the tip you hear a "beep" sound. This tells you that the probe is on.

You can also go to the I/O tab on the Diagnostics page. Monitor the value of the INPUT for the PROBE_SIGNAL. Use your finger to push on the tip on the tool probe.

If the probe operates correctly, the value of the INPUT for the PROBE_SIGNAL changes.

Step 2

Do this step to make sure the tool probe operates correctly:

Operate this code in MDI mode:

M59 P2;

G04 P1.;

M59 P3;

Use your finger to push on the tip on the table-mounted tool probe. When you push on the tip you hear a "beep" sound. This tells you that the probe is on.

You can also go to the I/O tab on the Diagnostics page. Monitor the value of the INPUT for the PROBE_SIGNAL. Use your finger to push on the tip on the tool probe.

If the probe operates correctly, the value of the INPUT for the PROBE_SIGNAL changes.

Next Generation Control - Tool Probe Calibration

This procedure tells you how to do calibrate the tool probe.

Step 1

Put the calibration tool in the spindle.

Jog the calibration tool to approximately 0.400" (10mm) above the tool probe stylus.

Push EDIT.

Use the LEFT or RIGHT CURSOR arrows to go to VPS.

Push ENTER.

Push the DOWN CURSOR arrow to select PROBING.

Push the RIGHT CURSOR arrow.

Step 2

Select CALIBRATION.

Push the RIGHT CURSOR arrow.

Step 3

Select Tool Probe Calibration.

Push the RIGHT CURSOR arrow.

Step 4

Enter the values for these variables:

  • K: CALIBRATION TOOL LENGTH
  • S: CALIBRATION TOOL DIAMETER
  • D: TABLE SIDE

Step 5

Push F4.

Select Output to MDI.

Push ENTER. This sends the code to the MDI window.

Push CYCLE START to operate the calibration program.

Next Generation Control - Work Probe Calibration

Step 1

Put the work probe into the spindle.

Measure the inside diameter of the ring gauge. Use an inside micrometer or a bore gauge. If the inside diameter is written on the gauge, record that number.

Step 2

Press EDIT. Press the UP ARROW cursor key and select VPS.

Select PROBING and then select CALIBRATION.

Select Spindle Probe Length Calibration [1].

Type in the tool number [2].

Press F4. Press 2 to send the generated code to MDI. Press CYCLE START to run the Spindle Probe Length Calibration.

Step 3

Press EDIT to return to the VPS menu.

Select PROBING and then select CALIBRATION.

Select Spindle Probe Diameter Calibration [1].

Type in the diameter you measured in Step 1 [2].

Press F4. Press 2 to send the generated code to MDI. Press CYCLE START to run the Spindle Probe Diameter Calibration.
