Tool offset
Some tool types require an offset for correct length measurement.
The following settings are available:
● Auto
With a tool that is larger than the probe, the tool edge is set on the center of the probe.
You can specify an offset correction in the ΔV input field. Select the direction and axis in
the adjacent selection field.
● Yes
The tool edge is positioned centrally on the probe.
You can specify an offset correction in the ΔV input field. Select the direction and axis in
the adjacent selection field.
● No
The tool is positioned centrally on the probe.
The fields for the offset correction and specification of the axis and direction are not
available.
If the measurement shows that the length of the tool diameter is greater than the probe
diameter, measurement is automatically performed with rotating spindle.
Individually checking teeth
Before or after machining you can check if any cutting edges of the milling tool have broken
off.
If it is noticed during the check of the cutting edges that not all cutting edges or teeth are
present, you will receive a corresponding message.
