Parameter Description
Machining The following machining operations can be selected:
∇ (roughing)
•
∇∇∇ base (base finishing)
•
∇∇∇ edge (edge finishing)
•
Chamfering
•
Z0 Reference point Z
Z1 Pocket depth (abs) or depth relative to Z0 (inc)
- (only for ∇, ∇∇∇ base or ∇∇∇ edge)
Maximum plane infeed
DXY •
Maximum plane infeed as a percentage of the milling cutter diameter
•
- (only for ∇ or ∇∇∇ base)
DZ Maximum depth infeed – (only for ∇ or ∇∇∇ edge)
UXY Plane finishing allowance – (only for ∇, ∇∇∇ base or ∇∇∇ edge)
UZ Depth finishing allowance – (only for ∇ or ∇∇∇ base)
Manually enter starting point
Starting point •
Automatically calculate starting point
•
- (only for ∇ or ∇∇∇ base)
XS Starting point X - (only when manually entering the starting point)
YS Starting point Y - (only when manually entering the 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 only be used only if the cutter can cut across center or if the
pocket has been predrilled.
Helical: 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 circle motion is executed to eliminate the inclined insertion path.
Oscillating: Insertion 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.
