8.12 Collision monitoring (CDON, CDOF, CDOF2)
Function
When CDON (Collision Detection ON) and tool radius compensation are active, the control
monitors the tool paths with Look Ahead contour calculation. This Look Ahead function
allows possible collisions to be detected in advance and permits the control to actively avoid
them.
When collision detection is off (CDOF), a search is made at inside corners in the previous
traversing block (and if necessary in blocks further back) for a common intersection point for
the current block. If no intersection is found with this method, an error is generated.
Programming
CDON
Or
CDOF
Or
CDOF2
Parameters
CDON
Activate bottleneck detection
CDOF
Deactivate bottleneck detection
CDOF2
Determine tool offset direction from adjacent block parts.
CDOF2 is active only for 3D circumferential milling.
