Parameter Description
α0 Angle of rotation
Z1 Slot depth (abs) or depth relative to Z0 (inc) – (only for ∇, ∇∇∇ and ∇∇∇ edge)
DXY
● Maximum plane infeed
(only for ShopMill)
● Maximum plane infeed as a percentage of the milling cutter diameter
- (only for ∇ and ∇∇∇)
DZ Maximum depth infeed - (only for ∇, ∇∇∇ and ∇∇∇ edge)
UXY Plane finishing allowance - (only for ∇, ∇∇∇ and ∇∇∇ edge)
UZ Depth finishing allowance (slot base) - (only for ∇ and ∇∇∇)
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.

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.
FZ Depth infeed rate – (only for vertical insertion)
(only for G code)
FZ Depth infeed rate – (only for vertical insertion)
(only for ShopMill)
EP Maximum pitch of helix – (only for helical insertion)
(only for G code)
ER Radius of helix – (only for helical insertion)
(only for G code) The radius cannot be any larger than the cutter radius; otherwise, material will remain.
EW Maximum insertion angle - (only for insertion with oscillation)
FS Chamfer width for chamfering (inc) - (only for chamfering)
ZFS Insertion depth of tool tip (abs or inc) - (only for chamfering)

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.
