10.5 Contour milling
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 referred to Z0
CP Positioning angle for machining area
- (only for ShopTurn, machining surface, face Y)
Angle CP does not have any effect on the machining position in relation to the workpiece.
It is only used to position the workpiece with the rotary axis C in such a way that machining
is possible on the machine.
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.
