Measuring the workpiece zero
3.6.1
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.
When the workpiece zero / zero offset is calculated, the tool length is automatically taken
into account.
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
● Offset target, global basic zero offset (only 840D sl)
● Offset target, channel-specific basic zero offset (only 840D sl)
Please refer to the machine manufacturer's specifications.
Logging the measurement result
After you have completed the measurement, you have the option to output the displayed
values in a log. You can define whether the log file that is generated is continually written to
for each new measurement, or is overwritten.
The requirement for measuring the workpiece is that a tool with known lengths is in the
machining position.
