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. 
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 (only for milling/turning machine) 
You can specify the tool offset data, i.e. the length, either manually or automatically using a 
tool probe.

2.5.1  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.
