Measuring variants
3.3 Measure workpiece (milling)
Note
The following measuring methods are only possible in the axes of the plane:
● 3D probe with spindle reversal (differential measurement)
● Align 3D probe
The probe types 712, 713 and 714 generally cannot be used for these measuring methods.
Starting position before the measurement
The probe should be positioned with the probe ball center in the measuring axis approximately
above the center of the rib. With the entered infeed path, it must be ensured that from the
starting height the required measuring height at the rib is 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
The probe ball is centered above the rib 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.
