Measuring Cycles for Milling and Machining Centers
5.2 CYCLE971 tool: Measuring milling tools, drills
Explanation of example
The tool probe is calibrated from the starting position in the –Z, +X, -X, +Y, -Y and again -Z
axes. The values are entered in the _TP field and _OVR field if the results (values of the
differences) are within the limits:
>_TZL, <_TSA.

Operational sequence

Position before measuring cycle call
The position before measuring cycle call can
be anywhere, but:
The cycle must be able to position the 1st
calibration point at distance _FA above the
center of the probe without collision.
The cycle approaches this point in the axis
sequence: applicate (tool axis) followed by
axis of the plane.
All subsequent traversing movements are
also performed by the measuring cycle with
"automatic calibration" using the values
entered in array _TP[ ] or TPW[ ] of the
probe and the dimensions of the active
calibration tool.
