Behavior when tool radius > circle radius

Function
With collision detection CDON on and active tool radius compensation, the CNC monitors tool paths through look-ahead contour calculation. Potential collisions are promptly identified in this way and actively prevented by the CNC.
The CNC detects the following critical machining situations, e.g., when the tool radius is too large, and effects compensation through tool path modification.
- Bottleneck detection
Because the tool radius is too large to produce a narrow inside contour, the bottleneck is bypassed and an alarm output.
- Contour path shorter than tool radius
The tool bypasses the workpiece corner on a transition circle, then continues on the programmed path.
- Tool radius too large for internal machining
In such cases, the contours are machined only as much as is possible without causing a contour violation.
