15.5 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 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", page 392) to the starting 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 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.
Please note while programming:
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.
