Touch Probe Cycles: Automatic Measurement of Workpiece Misalignment

13.2 BASIC ROTATION (Cycle 400, DIN/ISO: G400)

13.2 BASIC ROTATION (Cycle 400,
DIN/ISO: G400)

Cycle run

Touch probe cycle 400 determines a workpiece misalignment by
measuring two points, which must lie on a straight surface. With
the basic rotation function the TNC compensates the measured
value.
1 Following the positioning logic, the TNC positions the touch
probe at rapid traverse (value from FMAX column) (see
"Executing touch probe cycles", page 299) 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
performs the basic rotation.

Please note while programming:

Before a cycle definition you must have programmed
a tool call to define the touch probe axis.
The TNC will reset an active basic rotation at the
beginning of the cycle.
