Operational Sequence - Siemens SINUMERIK 840D sl Programming Manual

Explanation of example
The surface with position Z=-18 is approached in the Z axis in the minus direction
(_SETVAL=-18, _MA=1, _MD=1).
Actual calibration starts _FA=3 mm in front of the surface. The workpiece probe is then
calibrated and ends up facing the surface again at distance _FA from it. The new trigger
value in minus Z is entered in the data of probe 1 _WP[0,1] and in the result field _OVR[ ].
The original position is approached in block N40, N50.

Operational sequence

Position before measuring cycle call
The starting point must be a position facing the calibration surface.
Position after end of measuring cycle
On completion of calibration, the probe is positioned facing the calibration surface at
distance _FA.
