Measuring a tool with an 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 contact 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
● Before the actual measurement, enter approximate values for length and radius or
● Calibrate the probe first.
Lateral/longitudinal offset
If the widest part of the tool is not at the outer edge of the tool or the longest part is not at the
bottom edge of the tool, you can store this difference in the offset.
If measuring shows that the length of the tool diameter is greater than the probe diameter,
measurement is automatically performed with rotating spindle.
Tooth break monitoring
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.
