Parameter Description
DXY
(only for ShopTurn)
Maximum plane infeed
Maximum plane infeed as a percentage of the milling cutter diameter
- (only for ∇ and ∇∇∇)
mm
%
DZ Maximum depth infeed – (only for ∇ and ∇∇∇) mm
UXY Plane finishing allowance for the length (L) and width (W) of the slot (only for and ∇∇∇). mm
UZ Depth finishing allowance (tool axis) - (only for ∇ and ∇∇∇) mm
Insertion 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 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.
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.
(only for ShopTurn)
Clamp/release spindle (only for end face C/peripheral surface C, if inserted vertically)
The function must be set up by the machine manufacturer.
FZ
(only for G code)
Depth infeed rate – (for vertical insertion only) *
FZ
(only for ShopTurn)
Depth infeed rate - (only for insertion, predrilled and perpendicular) mm/min
mm/tooth
EP
(only for G code)
Maximum pitch of helix – (for helical insertion only) mm/rev
ER
(only for G code)
Radius of helix – (for helical insertion only)
The radius cannot be any larger than the milling cutter radius; otherwise, material will
remain.
mm
EW Maximum insertion angle – (for insertion with oscillation only) Degrees
FS Chamfer width for chamfering - (for chamfering only) mm
ZFS Insertion depth of tool tip (abs or inc) - (for chamfering only) mm
Programming technology functions (cycles)
