3.
Manual swivel
With "direct" swiveling enter the required rotary axis positions or with "axis by axis" the
required rotations (e.g. Y=-90) and <CYCLE START>.
4.
Measure workpiece
Apply "Set edge Z": The measured offset in Z is converted and entered as an X value in
the chosen work offset.
2.6.4
Calibrating the electronic workpiece probe
When the electronic probes are attached to the spindle, clamping tolerances usually occur.
This can lead to measurement errors.
In addition, you need to determine the trigger points of the probe relative to the spindle
center (trigger points).
Therefore, you need to calibrate the electronic probe. The radius is calibrated in a setting
ring (calibration ring) or a hole, the length is calibrated on a surface. The diameter of the
setting ring and the dimension of the surface in the Z direction (for G17) must be precisely
known and this is entered into the corresponding entry field when calibrating the probe. The
diameter of the workpiece probe ball and its length 1 must be stored in the tool list.
Procedure
1.
Load the workpiece probe into the spindle.
2.
Move the workpiece probe into the hole and position it in the
approximate center of the hole.
3.
Select "JOG" mode in the "Machine" operating area.
4..
Press the "Workpiece Zero" and "Calibrate Probe" softkeys.
The "Calibrate Probe" window opens.
5.
Press the "Length" or "Radius" softkey.
6.
In PL, select the working plane (e.g. G17...G19) and the effective work
offset during calibration (G54...G57).
