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 (siehe „Executing touch probe
cycles” auf Seite 334), the TNC po
sitions the touch probe to the
programmed probe starting point

1

at rapid traverse (value from

MP6150). The TNC offsets the touch probe by the set-up clearance
in the direction opposite to 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 touch point.

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.
