Measuring Cycles for Milling and Machining Centers
5.8 CYCLE961 workpiece: Setup inside and outside corner
Total measuring path: 2 · _FA in mm
is reached.
Otherwise, no measurement will be performed.
A minimum total measurement path of 2 · 20 mm is produced within a cycle.
Position before measuring cycle call
The probe is above the workpiece at positioning height. It must be possible to reach all
points without collision.
The measuring cycle generates the traversing blocks and performs the measurements at the
measuring points from points P1 to P4. The measuring depth is derived from the positioning
height lowered by the value in _ID (negative prefix). After measurement at one point the
probe is again raised to positioning height and traversed to the next point and then lowered
again to measuring depth.
Point P2 is approached first, followed by P1, P3, and P4.
Position after end of measuring cycle
The probe is at the positioning height at point P4.
