Parameter Description Unit
DXY
Maximum plane infeed
Maximum plane infeed as a percentage of the milling cutter diameter
- (only for ∇ or ∇∇∇ base)
mm
%
DZ Maximum depth infeed – (only for ∇ or ∇∇∇ edge) mm
UXY Plane finishing allowance – (only for ∇, ∇∇∇ base or ∇∇∇ edge) mm
UZ Depth finishing allowance – (only for ∇ or ∇∇∇ base) mm
Starting point
Manual
Starting point is manually entered
Automatic
Starting point is automatically calculated
- (only for ∇ or ∇∇∇ base)
XS Starting point X - (only for "manual" starting point)
YS Starting point Y - (only for "manual" starting point)
Insertion
The following insertion modes can be selected – (only for ∇ or ∇∇∇ base)
Perpendicular: Insert perpendicular to the center of pocket
The tool executes the calculated actual depth infeed at the pocket center in a single
block. This setting can be used only if the cutter can cut across center or if the
pocket has been predrilled.
Helical: Insert 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 circle motion is executed to eliminate the inclined insertion path.
Oscillating: Insert with oscillation along center axis of rectangular pocket
The cutter center point oscillates back and forth 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.
FZ (only for
ShopMill)
Depth infeed rate - (only for perpendicular insertion and ∇) mm/min
mm/tooth
FZ (only for G
code)
Depth infeed rate - (only for perpendicular insertion and ∇) mm/min
EP Maximum pitch of helix – (for helical insertion only) mm/rev
ER Radius of helix – (for helical insertion only)
The radius cannot be any larger than the cutter radius; otherwise, material will remain.
mm
EW Maximum insertion angle – (for insertion with oscillation only) Degrees
Lift mode
Lift mode before new infeed - (only for ∇, ∇∇∇ base or ∇∇∇ edge)
If the machining operation requires several points of insertion, the retraction height can
be programmed:
to RP
Z0 + safety clearance
When making the transition to the next insertion point, the tool returns to this height. If
there are no elements larger than Z0 in the pocket area, "Z0 + safety clearance" can be
selected as the lift mode.
mm
mm
FS Chamfer width for chamfering - (only for chamfering machining) mm
ZFS Insertion depth of tool tip (abs or inc) - (for machining only) mm
