Cycle run
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 (see “Executing touch probe
cycles” on page 306), the TNC positions the touch probe at rapid
traverse (value from MP6150 or MP6361) to the programmed
starting point
1 and measures the first touch 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
2 and measures the actual 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
3 and measures the actual value
of the third touch point.
4 Finally the TNC returns the touch probe to the clearance height and
saves the measured angle values in the following Q parameters:
