Insertion
The following insertion modes can be selected – (only for ∇, ∇∇∇ or ∇∇∇ edge):
•
Predrilled:
(only for G code)
With G0, the pocket center point is approached at the retraction plane level, and
then, from this position, also with G0, the axis travels to the reference point brought
forward by the safety clearance. The machining of the rectangular pocket is then
performed according to the selected insertion strategy, taking into account the pro-
grammed blank dimensions.
•
Vertical: Insert vertically at center of pocket
The tool executes the calculated actual depth infeed at the pocket center in a single
block. This setting can be used only if the cutter can cut across center or if the
pocket has been predrilled.
•
Helical: Insert along helical path
The cutter center point traverses along the helical path determined by the radius
and depth per revolution (helical path). If the depth for one infeed has been
reached, a full circle motion is executed to eliminate the inclined insertion path.
•
Oscillating: Insert with oscillation along center axis of rectangular pocket
(only for G
code)
The cutter center point oscillates back and forth along a linear path until it reaches
the depth infeed. When the depth has been reached, the path is traversed again
without depth infeed in order to eliminate the inclined insertion path.
