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 332), the TNC positions the touch probe at rapid traverse
(value from MP6150) 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:
