14.2 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 (see "Executing touch probe cycles"
on page 332), the TNC positions the touch probe to the
programmed probe starting point 1 at rapid traverse (value from
MP6150). 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 (MP6120).
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.

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.
