This tells you how to set Machine Rotary Zero Point (MRZP) Rough 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

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)

After calibrating the probe zero return all axes by pressing [ZERO RETURN], then [ALL], and then [A].

Check to see if VPS Editing is enabled by pressing [DIAGNOSTIC] and navigate to Parameters, then to Features. If it is not enabled contact your local HFO.

To calibrate MRZP press [EDIT] and navigate to VPS, then Probing, then Calibration, and then to MRZP Calibration. 

Select A-C or B-C Axis Rough Set

Dimension the Center Bore and set C equal to the Center Bore diameter.

Note: The Center Bore diameter may vary depending if the machine has a standard platter or Pallet Pool option.

Set H equal to the distance from the table to the rotary center point

• All Non Pallet Pool UMC's = 2.0"
• UMC-1000 Pallet Pool = 0.0"

Set D Approximate Angle for Z Probe Touch equal to 0.0

Set E Distance for Probe to Travel Past Bore Diameter equal to 0.25

Jog Probe to .1" above center of Platter Bore.

Press [CYCLE START] to begin probing cycle.

After the program is completed press [Current Commands] and navigate to Macro Variables.

Record the values for macro variables 10121, 10122, and 10123.

Press [Setting] and navigate to Machine Setup.

• Go to setting 255 MRZP X Offset and enter the value for macro variable 10121.
• Go to setting 256 MRZP Y Offset and enter the value for macro variable 10122.
• Go to setting 257 MRZP Z Offset and enter the value for macro variable 10123.
