4.6 Measuring the workpiece zero

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 or diameter 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.

Calibration of radius / diameter

Load the workpiece probe into the spindle.

Enter the approximate length and radius or diameter in the tool data.

Select the "JOG" mode in the "Machine" operating area.

Move the workpiece probe into the hole and position it at the approximate

center of the hole.

Press the "Workpiece zero" and "Probe calibration" softkeys.

The window "Calibration: Probe" is opened.

Press the "Radius" or "Diameter" softkey.

The "Diameter" softkey must be set up by the machine manufacturer.

In ∅, enter the calibration bore corresponding to the diameter.

Press the <CYCLE START> key.

Calibration starts.

When calibrating the radius, the exact hole center point is determined first.

Then the four trigger points on the inside wall of the hole are approached.

This procedure is carried out automatically twice: First with 180° (to the

starting position of the working spindle) and then in its starting position.
