Programming example
With the turning tool T3, D1 with SL=3, length L1 is to be determined incrementally and
machine-related.
The probe to be used is tool probe 1. This
probe is already calibrated in the minus X
direction (machine-related). The precise
values are entered in probe array _TP[0,2].

Explanation of example
The probe has been calibrated in minus X.
Before the program is started, the "tip" of the tool T3 is in measuring axis X in a range 2 ×
_FA=40 mm (dimension with reference to radius) in front of the probe. In axis Z, the center of
the cutting edge is centered with respect to the probe. If the cutting edge radius =0, it is the
tool nose.
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 x _FA = 40 mm. Otherwise, an alarm will be
triggered. Measurement is performed once (_NMSP=1).
After successful measurement, the "tip" of T3 is in the starting position again.
The calculated length L1 (tool type 5xy, _MA=2, _MVAR=xx0xxx) is entered in D1 of T3 in
the geometry. The associated wear component is reset.
