Filling out the program header
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.

5. Select a zero offset.
6. Enter the dimensions of the blank and the parameter, which are
effective over the complete program, e.g. dimension units in mm or
inch, tool axis, retraction plane, safety clearance and machining
direction.
Press the "Teach TC position" softkey if you want to set the actual
position of the tool as a tool change point.
The tool's coordinates are transferred into parameters XT and ZT.
Teaching in the tool change point is only possible if you have selected
the machine coordinate system (Machine).
7. Press the "Accept" softkey.
The process plan is displayed. Program header and end of program are
