Operational Sequence - Siemens SINUMERIK 840D sl Programming Manual

Explanation of example
On cycle call, the probe travels in the minus Z direction max. 24 mm (_FA=12) at measuring
feedrate 300 mm/min (_VMS=0, _FA>1). If the probe is triggered within this measuring path
of 24 mm, length 1 (geometry) is calculated and entered in tool offset memory T9, D1, D3.
The trigger value of probe 1 in the minus Z direction is used as the ball radius of the probe
from T9, D1, DP6 and then entered in _WP[0,5] – if _CBIT[14]=0.
If _CBIT[14]=1, this value is =0.

Operational sequence

Position before measuring cycle call
The probe should be positioned opposite the calibration surface such that it is deflected at
the start of the cycle within the max. measurement path of 2 × _FA [mm].
Position after end of measuring cycle
When the calibration procedure is completed the probe is positioned on the starting position.
