Measuring Cycles for Turning Machines
6.3 CYCLE982 tool: Measure turning and milling tools
Explanation of example
Before the program is started, the "tip" of the calibration tool T7 is in measuring axis X in a
range 2 · _FA=40 (dimension with reference to radius) in front of the probe. In axis Z, the
probe tip center is centered with respect to the probe.
When CYCLE982 is started, measurement starts in the negative X direction (_MA=2, MD=1)
with measuring velocity 300 mm/min (_VMS=0, _FA>1). The switching signal is expected by
the probe 1 (_PRNUM=1) within a distance of 2 · _FA=40 mm. Otherwise, an alarm will be
triggered. Measurement is performed once (_NMSP=1).
After successful measurement, the "tip" of T7 is in the starting position again.
The calculated probe value is entered in _TP[0,2]. Calibration with the measuring process
has been completed in minus X.

Operational sequence

Position before measuring cycle call
The calibration tool must be prepositioned as shown in the figure:
The "tip" of the calibration tool in the measuring axis _MA within distance 2 · _FA in front of
the measuring surface.
The center of the calibration tool tip in the other axis (offset axis) must be in the center of the
probe.
The measuring cycle starts measuring in the specified axis (_MA) and measuring direction
(_MD) immediately on starting.
