3.1 Measuring Workpiece Misalignment

8 Traversing to clearance height Q301: Definition of

how the touch probe is to move between the

measuring points:

0: Move at measuring height between measuring

points

1: Move at clearance height between measuring

points

8 Axis for compensation motion Q312: assignment of

the rotary axis in which the TNC is to compensate the

measured misalignment:

4: Compensate misalignment with rotary axis A

5: Compensate misalignment with rotary axis B

6: Compensate misalignment with rotary axis C

8 Set to zero after alignment Q337: Definition of

whether the TNC should set the display of the aligned

rotary axis to zero:

0: Do not reset the display of the rotary axis to 0 after

alignment

1:Reset the display of the rotary axis to 0 after

alignment

8 Number in table Q305: Enter the number in the

preset table/datum table in which the TNC is to set

the rotary axis to zero. Only effective if Q337 is set to

8 Measured-value transfer (0, 1) Q303: Specify if the

determined basic rotation is to be saved in the datum

table or in the preset table:

0: Write the measured basic rotation as a datum shift

in the active datum table. The reference system is the

active workpiece coordinate system.

1: Write the measured basic rotation into the preset

table. The reference system is the machine

coordinate system (REF system).

8 Reference angle? (0=ref. axis) Q380: Angle with

which the TNC is to align the probed straight line.

Only effective if the rotary axis C is selected

(Q312 = 6)
