Parameter Description
Approach Planar approach mode:
Straight line:
•
Slope in space
Quadrant:
•
Part of a spiral (only with path milling left and right of the contour)
Semi-circle:
•
Part of a spiral (only with path milling left and right of the contour)
Perpendicular:
•
Perpendicular to the path (only with path milling on the center-point path)
Approach strategy •
Axis by axis
Spatial (only for "quadrant, semi-circle or straight line" approach)
•
R1 Approach radius - (only for "quadrant or semi-circle" approach)
L1 Approach distance - (only for "straight line" approach)
Retraction Planar retraction mode:
Straight line
•
Quadrant:
•
Part of a spiral (only with path milling left and right of the contour)
Semi-circle:

strategy
Spatial (not with perpendicular approach mode)
•
R2 Retraction radius - (only for "quadrant or semi-circle" retraction)
L2 Retraction distance - (only for "straight line" retraction)
Lift mode If more than one depth infeed is necessary, specify the retraction height to which the
tool retracts between the individual infeeds (at the transition from the end of the contour
to the start).
