14.5 BASIC ROTATION compensation via
rotary axis (Cycle 403, DIN/ISO: G403)

Cycle run

Touch probe cycle 403 determines a workpiece misalignment by
measuring two points, which must lie on a straight line. The TNC
compensates the determined misalignment by rotating the A, B or
C axis. The workpiece can be clamped in any position on the rotary
table.
1 Following the positioning logic, the TNC positions the touch
probe at rapid traverse (value from FMAX column) (See
"Executing touch probe cycles", page 497) to the programmed
touch point 1. The TNC offsets the touch probe by the safety
clearance in the direction opposite to the defined traverse
direction.
2 Then the touch probe moves to the entered measuring height
and runs the first probing process at the probing feed rate
(column F).
3 Then the touch probe moves to the next starting position
probes the second position.
4 The TNC returns the touch probe to the clearance height and
rotates the rotary axis, which was defined in the cycle, by the
measured value. Optionally you can specify whether the TNC is
to set the determined rotation angle to 0 in the preset table or
in the datum table.
