Program test
To avoid program stops, the tool with the largest radius from the range of used tools should
always be used during the program test.
Examples of compensation motions for critical machining situations
The following examples show critical machining situations that are detected by the control
and compensated through modified tool paths. In all examples, a tool with too large a radius
has been used for the machining of the contour.
Example 1: Bottleneck detection
As the tool radius selected for the machining of this inside contour is too large, the
"bottleneck" is bypassed.
An alarm is output.
Example 2: Contour path shorter than tool radius
The tool bypasses the workpiece corner on a transition circle, then continues on the
programmed path.
