Parameter Description
Machining The following machining operations can be selected:
● ∇ (roughing)
● ∇∇∇ base (base finishing)
● ∇∇∇ edge (edge finishing)
● Chamfering
Z0 Reference point in the tool axis Z
Z1 Pocket depth (abs) or depth relative to Z0 (inc) - (only for ∇, ∇∇∇ base or ∇∇∇ edge)
DXY
● Maximum plane infeed
● Maximum plane infeed as a percentage of the milling cutter diameter
(only for ∇ or ∇∇∇ base)
DZ Maximum depth infeed – (only for ∇ and ∇∇∇ edge)
UXY Plane finishing allowance - (only for ∇, ∇∇∇ base or ∇∇∇ edge)
UZ Depth finishing allowance – (only for ∇ or ∇∇∇ base)
Insertion The following insertion modes can be selected – (only for ∇, ∇∇∇ base or ∇∇∇ edge):
● Vertical
● Helical
● Oscillation

*
The calculated actual infeed depth is machined at the calculated position.
Note:
This setting can be used only if the cutter can cut across center or if the pocket has
been predrilled.
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.
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.
