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:
Part of a spiral (only with path milling left and right of the contour)
Retraction strat‐
● Axis by axis
egy
● 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).
Lift mode before new infeed
● Z0 + safety clearance
● By the safety clearance
● to RP
● No retraction
FZ Depth infeed rate – (only for axis-by-axis approach strategy)
(only for ShopMill)
FZ - (only for G Depth infeed rate – (only for axis-by-axis approach strategy)
