Description
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.
Oscillation
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 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, material
will remain.
Maximum insertion angle – (for insertion with oscillation only)
Chamfer width for chamfering - (for chamfering only)
Insertion depth of tool tip (abs or inc) - (for chamfering only)
