Contour circular (with return)
The tool approaches the workpiece, executes the circular cut and
returns to the starting point at the end of cycle (see figures). Cutter
radius compensation is taken into account.
Type of machining for technology database access: Finishing
Cycle execution if "With return" is active
1 Move paraxially from the starting point to the contour starting
point X1, Z1
2 Move in circular arc to contour end point X2, Z2 at the
programmed feed rate
3 Retract and return on paraxial path to starting point
Cycle parameters
