You define the tool change point, the retraction plane, and the safety
distance in the program header (see Sec. "Creating a new program").

Approaching/retracting when taking a tailstock into consideration

The tool travels in rapid traverse from the tool change point along
the shortest path to the protective plane XR from the tailstock.

After this, the tool moves in rapid traverse on the retraction plane in
the X direction.

After this, the tool travels in rapid traverse to the safety distance.

Then the machining of the workpiece takes place with the
programmed machining feedrate.

After the machining, the tool retracts vertically in rapid traverse to
the safety distance.

Then the tool continues to travel vertically in rapid traverse to the
retraction plane.

After this, the tool travels in the direction X to the protective plane
XR from the tailstock.

From there, the tool travels in rapid traverse along the shortest
path to the tool change point.
If the tool does not need to be changed between two machining
processes, the tool travels from the retraction plane to the next
machining cycle.
You define the tool change point, the retraction plane, the safety
distance, and the protective area for the tailstock in the program
header (see Sec. "Creating a new program").
