Entering the calibration feedrate
The actual calibration feedrate can be entered into this entry field. The calibration feedrate is
stored in the calibration data and is used for the measurements.
If the entry field does not exist, then the calibration feedrate from a central parameter is
used.
Selecting the work offset as basis for the measurement
A work offset can be selected as measurement basis to flexibly adapt to the measuring
tasks.
If the work offset selection as measurement basis is not activated, then the measurement
refers to the currently active work offset.
Measuring sequence
To obtain the desired measuring results, you must keep to the measuring point sequence
shown in the help displays.
You can reject measuring points and then measure them again. This is done by pressing the
softkey that is currently active (measured value).
Measuring only
If you "only" want to measure the workpiece zero, the measured values are calculated and
displayed without changing the coordinate system.
Work offset
You usually store the measured workpiece zero in a work offset. The HMI allows rotations
and offsets to be measured.
Zero point
The measurement values for the offsets are stored in the coarse offset and the relevant fine
offsets are deleted. If the zero point is stored in a non-active work offset, an activation
window is displayed in which you can activate this work offset directly.
Aligning
Alignment can be performed either by rotating the coordinate system or by rotating the
workpiece with a rotary axis. If your machine is equipped with two rotary axes and the
"swivel" function is set up, you can also align an inclined plane.
