Parameter Description
UZ Depth finishing allowance (slot base) - (only for ∇ and ∇∇∇) mm
Insertion The following insertion modes can be selected:
● Predrilled: (only for G code)
Approach reference point shifted by the amount of the safety clearance with G0.
● Perpendicular:
ShopMill: Depending on the effective milling tool width (milling tool diameter x
DXY[%]) or DXY [mm]) the tool is moved to the infeed depth at the pocket center or
at the pocket edge.
– At the edge of the longitudinal slot ("inside left"): Effective milling tool width >=
half the slot width.
– At the longitudinal slot center: Effective milling tool width < half the slot width.
G code: The tool is inserted to the infeed depth at the reference point "inside left"
Note: This setting can be used only if the cutter can cut across center.
● Helical: Insertion on helical path (only for G code)
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 longitudinal slot is machined to eliminate the inclined insertion path.
● Oscillating: Insert with oscillation along center axis of longitudinal slot
The cutter center point oscillates 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 remove the slope caused by insertion.

Note
Predrilling position
The position at which insertion is performed if "predrilled" is selected, is the same position that
you select when specifying the reference point with "left inside". In the case of a slot without
an angle of rotation, the predrilled position is the center point of the left rounding radius of the
slot. When the cycle is called on a position circle, the predrilled position is always the center
point of the rounding radius that is closer to the center point.
