380 Touch Probe Cycles: Automatic Measurement of Workpiece Misalignment
15.2 BASIC ROTATION (Cycle 400, DIN/ISO: G400)
15.2 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 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
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.
