Siemens SINUMERIK 840D sl Programming Manual page 107

Preconditions
● The probe must be active as tool.
● Tool type of the probe:
Starting position before the measurement
The probe should be positioned with the probe ball center in the measuring axis
approximately at the center of the groove and at the measuring height. For a protection
zone, the probe ball should be positioned in the measuring axis approximately centered to
the groove and 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
groove 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, the probe ball is at the measuring height in the center of
the groove. With protection zone, the probe ball is centered with respect to the groove over
the protection zone at 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.
