Starting position before the measurement
For a hole (parallel with the axis), without a protection zone, the probe should be positioned
with the probe ball center at approximately the center of the hole at the measuring height.
For a protection zone, the probe ball center is positioned approximately centered to the hole
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 hole can be reached.
NOTICE
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 hole.
With a protection zone, the measuring cycle end position of the probe ball is centered above
the hole at the height of the starting position.
NOTICE
The range of the measuring cycle starting points with regard to the hole center point must
be within the value of the measuring path DFA, otherwise, there is danger of collision or the
measurement cannot be performed!
Procedure
The part program or ShopMill program to be processed has been created and you are in the
editor.
