Hole - rectangular pocket (CYCLE977)

Function
This measuring variant can be used to measure a rectangular pocket in a workpiece. The
pocket width and the pocket length are measured and the pocket center point is determined.
The measurements are always performed parallel to the geometry axis of the active plane.
Measurements are also possible at a rectangular pocket rotated around the infeed axis. To do
this, an angle corresponding to the real pocket position must be entered into the
parameterization screen form. Probing at the sides of the pocket is always at right angles to
these. A protection zone can be defined in the pocket.
With the "3D probe with spindle reversal" measuring method, measurement is performed in
the axes of the plane as differential measurement. Two complete measurements of the
rectangular pocket are automatically carried out one after the other, one with a spindle position
of 180 degrees, and one with 0 degrees. The special procedure for this measurement permits
the use of an uncalibrated multi-directional probe. However, the correct tool radius of the probe
must be determined once by calibrating the probe. Probe types 712, 713 and 714 are not
suitable for this purpose. A positionable spindle is mandatory.
With the "Align 3D probe" measuring method, the switching direction of the probe is always
aligned to the current measuring direction. This function is recommended when high demands
are placed on the measuring accuracy. Probe types 712, 713 and 714 are not suitable for this
purpose. A positionable spindle is mandatory.
The measurement result (measurement difference) can be used as follows:
● Correction of a WO so that the workpiece zero is in relation to the center point of the
rectangle
● Offset of a tool
● Measurement without offset
