334 Touch Probe Cycles: Automatic Measurement of Workpiece Misalignment
14.5 BASIC ROTATION Compensation via Rotary Axis (Cycle 403, DIN/ISO:
G403)
U Clearance height Q260 (absolute): Coordinate in the
touch probe axis at which no collision between touch
probe and workpiece (fixtures) can occur. Input range
-99999.9999 to 99999.9999, alternatively PREDEF
U 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
U 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
U 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
U 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
1. Input range 0 to 2999
U 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).
U 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). Input range -360.000 to 360.000
