2.5 Measuring the tool

2.5 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.
You can determine the tool offset data, i.e. the length and radius or diameter, either manually
or automatically with tool probes.

Measuring a tool manually

For manual measurement, move the tool manually to a known reference point to determine
the tool length and the radius or diameter. The control then calculates the tool offset data
from the position of the tool carrier reference point and the reference point.
Reference point
When measuring the tool length you can either use the workpiece or a fixed point in the
machine coordinate system, e.g. a mechanical test socket or a fixed point in combination
with a distance gauge as the reference point.
When determining the radius/diameter, the workpiece is always used as the reference point
In the machine data, you define whether the radius or the diameter of the tool is to be
measured.
Note
You can enter the position of the workpiece during measurement.
However, you must declare the position of the fixed point before the measurement.
