Starting position before the measurement
The probe must be positioned at the position setpoint of the pocket center point. This position
approached in the pocket represents the starting position and at the same time the setpoint
for the offsets to be determined. For a protection zone, the position of the probe ball is at a
height above the protection zone.
With the infeed path that has been entered, it must be guaranteed that from this height the
desired measuring height in the pocket can be reached.
Note
If too large a measurement path DFA has been selected so that the protection zone is violated,
then the distance is reduced automatically in the cycle. However, there must be sufficient room
for the probe ball.
Position after the end of the measuring cycle
Without activated protection zone, at the end of the measuring cycle, the probe ball is at the
measuring height in the center of the pocket.
With a protection zone, at the end of the measuring cycle, the probe ball is centered above
the pocket at the height of the starting position of the measuring cycles.
Procedure
The part program or ShopMill program to be processed has been created and you are in the
editor.
