Linear machining, longitudinal
Call the single-cut menu
Select longitudinal linear machining
 Off: When the cycle is completed, the tool remains
at the cycle end position
 On: Tool returns to the starting point
Linear machining, longitudinal
The tool moves from the starting point to the contour end point Z2 at
the programmed feed rate and remains at the cycle end position.
Contour linear, longitudinal
(with return)
The tool approaches the workpiece, executes the longitudinal cut and
returns to the starting point at the end of cycle (see figures).
Type of machining for technology database access: Finishing
Cycle execution if "With return" is active
1 Move from the starting point to the contour starting point X1
2 Move to contour end point Z2 at the programmed feed rate
3 Retract and return on paraxial path to starting point
