9.2 UMC 500/750/1000 - MRZP WIPS 偏置设置

This tells you how to set Machine Rotary Zero Point (MRZP) Offsets. The MRZP Offsets are settings in the Haas CNC control that tell the control these distances:

1. the distance of the tilt axis (B axis) centerline from the X-Axis home position
2. the distance of the tilt axis (B axis) centerline from the Z-Axis home position
3. the distance of the table rotary axis (C axis) centerline from the Y-Axis home position

This procedure shows images that use both calibration assemblies.

 Important: The spindle probe must be calibrated before doing this procedure. This makes sure the accuracy of the probe to the machine position is correct. Refer to the Next Generation Control - Probe Calibration (VPS) procedure, in the diy.haascnc.com

Press [Setting] and navigate to Machine Setup. Check settings 255, 256, and 257. The values should not be zero. If they are perform the following procedure.

[ZERO RETURN] [ALL] axes.

Go to Features tab in [DIAGNOSTIC] and make sure the VPS Editing is on.

Put the work probe in the spindle.

Push [EDIT] button.

Select VPS .

Push the [DOWN] cursor arrow to PROBING [1].

Select CALIBRATION [2]. Push the [RIGHT] cursor arrow.

Select MRZP CALIBRATION [3].

Push the [DOWN] cursor arrow and select B-AXIS TILT C-AXIS ROTARY FINISH SET.

Note: A-C Or B-C MRZP ROUGH SET is used only when there are no MZRP offset settings (255, 256, 257) set.

Enter the diameter of the tooling ball [2].

Important: Always measure the tooling ball with a calibrated micrometer to ensure the correct ball diameter.

 Note: If you are in metric mode make sure you enter the ball size in millimeters. If you are in inch mode enter the ball size in inches

Push [ENTER] .

Push [F4] .

Select Output MDI .

Install the calibration sphere assembly [1] near the center of the platter.

Note:  On a UMC-1000 if the calibration sphere is too far out from the center, an overtravel alarm will be generated during the MRZP calibration cycle.

Make sure that the tooling ball [2] is tightly attached to the calibration assembly.

Note:  On UMC machines that are equipped with the Pallet Pool the calibration sphere will need to be secured to the pallet using toe clamps.

Note: Do not over-tighten the tooling ball.

Jog the Z Axis until the probe tip [2] is 0.1" (2.54 mm) above and centered over the tooling ball [1].

Start the program in MDI. This program is O099994 B AXIS TILT AND C AXIS ROT AXIS .

The probe measures many positions on the B and C axes at different degrees.

The program puts values in macro variables 10121, 10122, and 10123. Record those values.

Put the recorded values in these settings:

• Enter the value for macro variable 10121 in setting 255; MRZP X Offset.
• Enter the value for macro variable 10122 in setting 256; MRZP Y Offset.
• Enter the value for macro variable 10123 in setting 257; MRZP Z Offset.

If you think that you possibly entered incorrect numbers, start the MRZP FINISH SET program again. The values that the program puts into the variables must be within five counts or less of the setting numbers.

 Note: Setting 9 determines if the values are shown in inches or millimeters.
