UXY Finishing allowance on edge (not applicable to center-point path machining
operations) (not for chamfer)
Approach Quadrant: Part of a spiral (only with path milling left and right of the contour)
mode Semicircle: Part of a spiral (only with path milling left and right of the contour)
Linear: Slope in space
Perpendicular: Perpendicular to the path (only with path milling on the center path)
Approach
strategy
R1 or L1 Approach radius (only for path milling on left and right of contour), approach length
Retract mode Quadrant: Part of a spiral (only with path milling left and right of the contour)
Semicircle: Part of a spiral (only with path milling left and right of the contour)
Linear: Slope in space
Perpendicular: Perpendicular to the path (only with path milling on the center path)
Retract
strategy
R2 or L2 Retract radius (only for path milling on left and right of contour), retract length
Retraction If more than one depth infeed is necessary, specify the retraction height to which the
mode tool retracts between the separate infeeds (in the transition from the end of the
contour to the beginning).
