Approach Approach mode:
mode In a quadrant: Part of a spiral (only with path milling left and right of the contour)
In a semicircle: Part of a spiral (only with path milling left and right of the contour)
In a straight line: Slope in space
Perpendicular: Perpendicular to the path (only with path milling on the center path)
Approach
strategy
R1 Approach radius (only for quadrant or semicircle approach mode)
L1 Approach distance (only for straight-line approach mode)
FZ Depth infeed feedrate
(for end face/end face C and end face Y with axis-by-axis approach strategy)
FX Depth infeed feedrate
(for peripheral surface/peripheral surface C and peripheral surface Y with axis-by-
axis approach strategy)
Retract mode Retract mode
In a quadrant: Part of a spiral (only with path milling left and right of the contour)
In a semicircle: Part of a spiral (only with path milling left and right of the contour)
In a straight line: Slope in space
Perpendicular: Perpendicular to the path (only with path milling on the center path)
Retract
strategy
R2 Retraction radius (only for quadrant or semicircle retraction mode)
L2 Retraction distance (only for straight-line retraction mode)
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).
