Parameter Description Unit
Machining
● ∇ (roughing, plane-by-plane or helical)
● ∇∇∇ (finishing, plane-by-plane or helical)
● ∇∇∇ edge (edge finishing, plane-by-plane or helical)
● Chamfering
Machining type
● Plane-by-plane
Machine circular pocket plane-by-plane
● Helical
Machine circular pocket using helical type
Machining posi‐
tion
● Single position
A circular pocket is machined at the programmed position (X0, Y0, Z0).
● Position pattern
Several circular pockets are machined in a position pattern
(e.g. full circle, pitch circle, grid, etc.).
X0
Y0
Z0
The reference points refer to the center point of the circular pocket:
Reference point X – (for single position only)
Reference point Y – (for single position only)
Reference point Z – (single position only and G Code position pattern)

∅ Diameter of pocket mm
Z1 Pocket depth (abs) or depth relative to Z0 (inc) – (only for ∇, ∇∇∇ and ∇∇∇
edge)
mm
DXY
● Maximum plane infeed
● Maximum plane infeed as a percentage of the milling cutter diameter
- (only for ∇ and ∇∇∇)

DZ Maximum depth infeed - (only for ∇, ∇∇∇ and ∇∇∇ Rand) mm
UXY Plane finishing allowance - (only for ∇, ∇∇∇ and ∇∇∇ edge) mm
UZ Depth finishing allowance – (only for ∇ and ∇∇∇) mm
Insertion Various insertion modes can be selected – (only for plane-by-plane machin‐
ing method and for ∇, ∇∇∇ or ∇∇∇ edge):
● Predrilled (only for G code)
● Perpendicular: Insert vertically at the center of pocket
The tool executes the calculated depth infeed vertically in the center of
the pocket.
Feedrate: Infeed rate as programmed under FZ
● Helical: Insert along helical path
The cutter center point traverses along the helical path determined by the
radius and depth per revolution. If the depth for one infeed has been
reached, a full circle motion is executed to eliminate the inclined insertion
path.
Feedrate: Machining feedrate
Note: The vertical insertion into pocket center method can be used only
if the tool can cut across center or if the workpiece has been predrilled.
