Parameter Description
CP Positioning angle for machining area
- (only for ShopTurn, machining surface, face Y)
C0 Positioning angle for machining surface
- (only for ShopTurn, machining surface, peripheral surface Y)
DXY
Maximum plane infeed
•
Maximum plane infeed as a percentage of the milling cutter diameter
•
DZ Maximum depth infeed
UXY Finishing allowance, plane
UZ Finishing allowance, depth
Starting point
Manual
•
Starting point is entered
Automatic
•
Starting point is automatically calculated
XS Starting point X - (only for "manual" starting point)
YS Starting point X - (only for "manual" starting point)
Insertion The following insertion modes can be selected – (only for ∇, ∇∇∇ base or ∇∇∇ edge):
Vertical insertion
•
The calculated actual 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
•
Insertion along a 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
•
Oscillating insertion at the center axis of the 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 Depth infeed rate – (for vertical insertion only)
ShopTurn)
FZ (only for G Depth infeed rate – (for vertical insertion only)
code)
EP Maximum pitch of helix – (for helical insertion only)
ER Radius of helix – (for helical insertion only)
The radius cannot be any larger than the milling cutter radius; otherwise, material will
remain.
