Retraction 
mode
 
If more than one insertion point is necessary, specify the retraction height to which 
the tool retracts between insertion points: 
   To retraction plane 
   Z0+safety clearance (for end face/end face C and end face Y only) or  
X0+safety clearance (for peripheral surface/peripheral surface C and peripheral 
surface Y only) 
If there are no islands larger than Z0 (X0) in the pocket area, Z0 + safety clearance 
(X0 + safety clearance) can be programmed as the retraction mode.
