The retraction for a cycle ends at the safety clearance. Only the subsequent cycle moves to
the retraction plane. This enables a special approach/retraction cycle to be used.
Changes to the retraction plane therefore take effect when retracting from the previous
machining operation.
When selecting the traversing paths, the tool tip is always taken into account; i.e. the tool
expansion is not considered. Therefore, you should ensure that the retraction planes are an
appropriate distance away from the workpiece. The retraction planes refer to the workpiece.
As a consequence, they are not influenced by a programmable offset.
