Description
Plane
Spatial (only for "quadrant, semi-circle or straight line" approach)
Approach radius - (only for "quadrant or semi-circle" approach)
Approach distance - (only for "straight line" approach)
Planar retraction mode:
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)
Straight line:
•
Plane
•
Spatial (not with perpendicular approach mode)
•
Retraction radius - (only for "quadrant or semi-circle" retraction)
Retraction distance - (only for "straight line" retraction)
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).
