Measuring the drilling and milling tool length with electrical tool probe

For automatic measurement, you determine the length and radius or diameter of the tool with
the aid of a tool probe (table probe system). The control uses the known positions of the
toolholder reference point and tool probe to calculate the tool offset data.
Use the softkey to select whether you want to measure the length, the radius or the diameter
of the tool.
The corresponding windows can be adapted to the measurement tasks in order to
automatically measure tools.
Adapting the user interface to calibrating and measuring functions
The following selection options can be switched-in or switched-out:
● Calibration plane, measurement plane
● Probe
● Calibration feedrate (measuring feedrate)
Requirements
● No function-related settings are necessary after the measuring cycles have been installed.
● Before the actual measurement, enter approximate values for length, radius or diameter of
the tool in the tool list.
● Calibrate the probe first.
