4.6 Measuring the workpiece zero
4.6.1 Measuring the workpiece zero
The reference point for programming a workpiece is always the workpiece zero. To determine
this zero point, measure the length of the workpiece and save the position of the cylinder's
face surface in the direction Z in a zero offset. This means that the position is stored in the
coarse offset and existing values in the fine offset are deleted.
Calculation
When the workpiece zero / zero offset is calculated, the tool length is automatically taken into
account.
Measuring only
If you wish to measure the workpiece zero in "Measuring Only" mode, the measured values
are merely displayed without any changes being made to the coordinate system.
Adapting the user interface to the measurement functions
The following selection options can be switched-in or switched-out:
● Calibration plane, measuring plane (only 840D sl)
● Zero offset as basis for the measuring process (only 840D sl)
● Number of the probe calibration data record (only 840D sl)
● Offset target, settable zero offset
● Offset target, basis reference
