Measuring Cycles for Milling and Machining Centers
5.3 CYCLE976 calibrate workpiece probe
Explanation of example
The hole center is determined twice, the spindle with the probe being rotated through 180°
between each measurement if a multi probe is used, in order to record any positional
deviation (skew) of the measuring probe. Triggering is then determined in all 4 axis
The new trigger values in -X, +X, -Y and +Y are stored in the global data of probe
2_WP[1,1...4], the positional deviation in the X and Y direction in _WP[1,7], _WP[1,8], the
active probe ball diameter in _WP[1,0].
The calculated hole center is entered in OVR, OVR.
Position before measuring cycle call
The probe must be positioned near the hole center in the abscissa and the ordinate of the
selected measuring plane and at the calibration height in the hole.
Axis sequence, axis direction sequence
● At an angle:
Calibration always starts in the positive axis direction, first in the abscissa, then in the
The axes always travel in combination acc. to starting angle _STA1, _STA1+180 degrees,
_STA1+90 degrees, and _STA1+270 degrees.
Otherwise, the same principle as for "paraxial" applies.
