3.5 Measuring the tool

3.5 Measuring the tool
The geometries of the machining tool must be taken into consideration when executing a
part program. These are stored as tool offset data in the tool list. Each time the tool is called,
the control considers the tool offset data.
When programming the part program, you only need to enter the workpiece dimensions from
the production drawing. After this, the controller independently calculates the individual tool
path.
Drilling and milling tools
You can determine the tool offset data, i.e. the length and radius or diameter, either manually
or automatically with tool probes.
Turning tools
You can specify the tool offset data, i.e. the length, either manually or automatically using a
tool probe.
Logging measurement results
After you have completed the measurement, you have the option to output the displayed
values to a log. You can define whether the log file that is generated is continually written to
for each new measurement, or is overwritten.

Measuring a tool manually

When measuring manually, traverse the tool manually to a known reference point in order to
determine the tool dimensions in the X and Z directions. The control system then calculates
the tool offset data from the position of the tool carrier reference point and the reference
point.
Reference point
The workpiece edge is used as the reference point when measuring length X and length Z.
The chuck of the main or counterspindle can also be used when measuring in the Z
direction.
