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 surface. 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 The TNC positions the touch probe at rapid traverse (value from
FMAX
column) following the positioning logic (see "Executing touch
probe cycles" on page 373) to the programmed starting point 1 .
The TNC offsets the touch probe by the safety clearance in the
direction opposite the defined traverse direction.
2 Then the touch probe moves to the entered measuring height and
probes the first touch point at the probing feed rate (column F).
3 Then the touch probe moves to the next starting position 2 and
probes the second position.
4 The TNC returns the touch probe to the clearance height and
moves the rotary axis, which was defined in the cycle, by the
measured value. Optionally you can have the display set to 0 after
alignment.

Danger of collision!
The TNC does not check whether touch points and
compensation axis match. This can result in compensation
movements offset by 180°.
Before a cycle definition you must have programmed a
tool call to define the touch probe axis.
The TNC stores the measured angle in parameter Q150.
