14.2 BASIC ROTATION (Cycle 400, DIN/

ISO: G400, software option 17)

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", page 280) 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

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.
