Description
Plane finishing allowance for the length (L) and width (W) of the slot.
- (only for ∇ and ∇∇∇)
Depth finishing allowance (tool axis) - (only for ∇ and ∇∇∇)
The following insertion modes can be selected – (only for ∇, ∇∇∇ or ∇∇∇ edge):
Predrilled (only for G code)
•
Approach reference point shifted by the amount of the safety clearance with
G0.
Vertical
•
ShopTurn: Depending on the effective milling tool width (milling tool diameter
x DXY[%]) or DXY [mm] – at the pocket center or at the pocket edge, is
moved to the infeed depth.
– 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 (only for G code)
•
Insertion along helical path:
The cutter center point traverses along the helical path determined by the ra-
dius 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 in-
sertion 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 with-
out depth infeed in order to eliminate the inclined insertion path.
Clamp/release spindle (only for end face C/peripheral surface C, if inserted verti-
cally)
The function must be set up by the machine manufacturer.
Depth infeed rate – (for vertical insertion only)
Depth infeed rate - (only for insertion, predrilled and perpendicular)
Maximum pitch of helix – (for helical insertion only)
Radius of helix – (for helical insertion only)
The radius cannot be any larger than the milling cutter radius; otherwise, materi-
al will remain.
Maximum insertion angle – (for insertion with oscillation only)
