intersection.
G462 Insertion of a straight line in the TRC block if no
intersection point is possible; the block is extended by
its end tangent (default setting)
Machining is done up to the extension of the last contour
element (i.e. up to just before the contour end).
Further information
The approach behavior is symmetrical to the retraction behavior.
The approach/retraction behavior is determined by the state of the G command in the
approach/retraction block. The approach behavior can therefore be set independently of the
retraction behavior.
Example of retraction behavior with G460
The following example describes only the situation for deactivation of tool radius
compensation. The behavior for approach is the same.
