16.13 MEASURE PLANE (Cycle 431,

DIN/ISO: G431)

Touch Probe Cycle 431 finds the angle of a plane by measuring

three points. It saves the measured values in system parameters.

1 Following the positioning logic, the TNC positions the touch

probe at rapid traverse (value from FMAX column) (See

"Executing touch probe cycles", page 497) to the programmed

and measures the first point of the plane. The TNC

offsets the touch probe by the safety clearance in the direction

opposite to the direction of probing.

2 The touch probe returns to the clearance height and then moves

in the working plane to starting point

value of the second touch point of the plane.

3 The touch probe returns to the clearance height and then moves

in the working plane to starting point

value of the third touch point of the plane.

4 Finally the TNC returns the touch probe to the clearance

height and saves the measured angle values in the following Q
