WIPS - Calibration - Introduction

This procedure tells you how to calibrate the Wireless Intuitive Probe System (WIPS). Calibrate the probe every (6) months. Also, calibrate the probe for each of these conditions:
  • Before you use the probe on tools or parts.
  • After a crash, or when you replace the probe.

 

  • Work probe [1]
  • OMI sensor [2]
  • Tool probe [3]

 

Tools Required

Dial indicator accturate to 0.0005" (0.013mm)
Calibration bar
Ring gauge
Digital micrometer

WIPS - Probe Operation Test

Step 1

Operate this code in MDI mode:

M59 P1133; G04 P1.0; M59 P1134;

When the control shows PROGRAM END, lightly tap the stylus [1] of the tool probe with your finger. The control makes a "beep" each time you touch the stylus. This starts the probe operation program.

Push RESET to stop the program.

Operate this code in MDI mode:

M59 P1134;

Hold the work probe [3] near the OMI sensor [2].

Push and hold CYCLE START.

Lightly tap the stylus [4] of the work probe. The control makes a "beep" sound. This tells you that the probe is started.

WIPS - Work Probe Stylus - Runout - Adjustment

Step 1

Put the work probe into the spindle.

Put the indicator onto the table. Align the indicator tip to the probe stylus [1] as shown.

Jog the spindle in 0.0001" increments until the indicator [2] touches the stylus. Set the indicator to 0.

Push EMERGENCY STOP.

Turn the spindle with your hand to measure the work probe runout. If the runout is more than 0.0001" (0.025 mm), do Step 2.

Step 2

If the runout is more than 0.0001" (0.025 mm), do these steps to adjust the work probe stylus:

  • Loosen the (2) top locking set screws [1] on the spindle probe. These screws lock the stylus in position. Lightly tighten them again.
  • Loosen the (4) bottom set screws [2] a small amount. These screws adjust the position of the stylus.
  • Turn the spindle with your hand until you find the highest indicator reading. This tells you which direction to adjust the stylus to decrease runout.
  • Tighten the bottom screws [3] on the high side. As you tighten these screws, loosen the bottom screws on the opposite side [4] to allow the stylus to move.

    note: Very small adjustments have a large effect on the stylus runout.
  • Adjust the screws until the runout is less than 0.0001" (0.025 mm).
  • Tighten these screws equally:
    • the top locking screw
    • the bottom adjustment screw on the opposite side

WIPS - Tool Probe - Calibration

Step 1

Put the calibration bar [1] into the spindle.

Use the indicator to measure the runout of the calibration bar.

If the runout is more 0.0001" (0.025 mm), adjust or replace the calibration bar.

If you have recorded the length of the calibration bar, do Step 2.

Do these step to measure the length of the calibration bar:

  • Put the tip of the indicator against the bottom face [2] of the calibration bar. Set the indicator to 0.
  • In MDI mode, jog the X Axis until the indicator is no longer under the calibration tool.
  • Jog the Z Axis in the negative (-) direction until the tip of the indicator touches the bottom face [3] of the spindle.
  • The Z-Axis value on the DIST TO GO position is the calibration bar length. Record this value.
  • Use a micrometer to measure the diameter of the widest part of the calibration bar. Record the measurement.

Step 2

In MDI mode, push PRGRM/CONVRS. Select the SET-UP tab. Push WRITE/ENTER.

Select the TOOL PROBE CALIBRATION tab.

Jog the Z Axis until the calibration bar [1] is 0.40" (10 mm) above the tool probe [2].

Do these steps to align the calibration bar to the tool probe:

  • Jog the X Axis until the calibration bar is aligned with the tool probe.
  • Push F1.
  • Jog the Y Axis until the calibration bar is aligned with the tool probe.
  • Push F1.
  • Enter this information for the calibration bar:
    • the tool number [3]
    • the bar length [4]
    • the bar diameter [5]
note: If you do not see the probe calibration tabs or intuitive programming system, you must enable the IPS probe. Set Parameter 732, IPS PROBE, to 2.

Push CYCLE START.

The Calibration Box shows COMPLETED.

Step 3

Attach the ring gauge [3] to the table near the tool probe.

Move the calibration bar [1] above the edge of the ring gauge.

Put a shim, feeler gauge, or slip of paper [2] over the gauge.

Push .0001/.1.
Jog the Z Axis until the tip of the calibration bar lightly touches the paper.
Push PRGRM/CONVRS. Select WORK PROBE CALIB.
Push F1 to enter the Z-Axis position.
Enter the length of the calibration bar. Push WRITE/ENTER.

Measure the thickness of the shim used. For example, a piece of paper at 0.003 inch.

Enter the thickness in the SHIM field [4]. Push WRITE/ENTER.

WIPS - Work Probe - Calibration

Step 1

Select the WORK PROBE CALIBRATION tab.

Put the work probe [1] into the spindle.

Measure the length [2] of the work probe. Enter the length of the work probe.

Enter the diameter of the ball at the end of the work probe. For the standard Renishaw probe, use 0.2362" (6 mm).

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, use that number.

Enter the diameter of the ring gauge. Push WRITE/ENTER.
Jog the axes until the work probe is approximately 0.3" (7 mm) above the center of the ring gauge [3].
Push CYCLE START.

The calibration box shows COMPLETED.

Be aware: Many service and repair procedures should be done only by authorized personnel. The service technicians at your Haas Factory Outlet (HFO) have the training, experience, and are certified to do these tasks safely and correctly. You should not do machine repair or service procedures unless you are qualified and knowledgeable about the processes.

Danger: Some service procedures can be dangerous or life-threatening. DO NOT attempt a procedure that you do not completely understand. Contact your Haas Factory Outlet (HFO) and schedule a service technician visit if you have any doubts about doing a procedure.
