Siemens SINUMERIK 880 GA2

8 Automatic Workpiece Measurement in JOG Mode (SINUMERIK 840 SW2) 08.96
8.3 Calibrating probe in any hole
Once calibration type plane or drilling axis (Version 3.5 and higher) has been selected the only
parameter that has to be entered is the setpoint diameter or the floor of the hole. The probe
must be positioned in the centre of the hole at the calibrating depth.
The hole centre or the hole floor must be known. If this is not the case or the determined
TRIGGERING points are very different, the centre point of the hole must be determined with
measuring variant "Measure hole" or the hole floor must be determined with the measuring
version "Measure surface" in the applicate. Calibration then has to be repeated.
When you press the softkey "CALIBRATION START" the control automatically switches to
"AUTOMATIC" mode and measuring cycle L887 is selected. The measuring cycle is
processed when "NC START" is operated. The determined trigger points are automatically
stored in the relevant MDC area. The probe is located at the centre of the hole on completion
of calibration. The control automatically switches to JOG mode and the selection display
"WORKPIECE MEASUREMENT" appears on the screen. The determined trigger points are
displayed when the softkey "CALIBRATION" is pressed.
