Parameter Description
Machining The following machining operations can be selected:
∇ (roughing)
•
∇∇∇ base (base finishing)
•
∇∇∇ edge (edge finishing)
•
• Chamfering
Z0 Reference point in the tool axis Z
Z1 Pocket depth (abs) or depth relative to Z0 (inc)
- (only for ∇, ∇∇∇ base or ∇∇∇ edge)
DXY
Maximum plane infeed
•
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)
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 ∇, ∇∇∇ base or ∇∇∇ edge):
Vertical insertion
•
The calculated current infeed depth is executed at the calculated position for
"automatic" starting point – or at the specified position for "manual" starting point.
Note:
This setting can be used only if the cutter can cut across center or if the pocket has
been predrilled.
Helical insertion
•
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
•
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 Depth infeed rate – (only for perpendicular insertion and ∇)
ShopMill)
FZ (only for G Depth infeed rate – (only for perpendicular insertion and ∇)
code)
EP Maximum pitch of helix – (for helical insertion only)
