Peripheral surface Y:
The positions refer to the reference point:
Positioning angle for machining surface – (only for single position)
Reference point Y – (only for single position)
Reference point Z – (only for single position)
Reference point X – (only for single position)

Z1
Pocket depth (abs) or depth relative to Z0/X0 (inc) – (only for ∇, ∇∇∇ and ∇∇∇ edge) mm

• Maximum plane infeed
• Maximum plane infeed as a percentage of the milling cutter diameter
- (only for ∇ and ∇∇∇)

Insertion
Various insertion modes can be selected – (only for plane-by-plane machining method
and for ∇, ∇∇∇ and ∇∇∇ edge):
•
Predrilled
(only for G code)
•
Vertical: Insert vertically at center of pocket
The tool executes the calculated depth infeed vertically at 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.

Turn)
Clamp/release spindle (only for end face C/peripheral surface C, if inserted vertically)
The function must be set up by the machine manufacturer.
FZ
(only for G code)
Depth infeed rate – (for vertical insertion only) *
FZ
(only for Shop-
Turn)
Depth infeed rate – (for vertical insertion only) mm/min
mm/tooth
EP Maximum pitch of helix - (for helical insertion only)
The helix pitch may be lower due to the geometrical situation.
