Parameter Description Unit
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.
(only for
ShopTurn)
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
ShopTurn)
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.
mm/rev
ER Radius of helix - (only for helical insertion)
The radius must not be larger than the milling cutter radius, otherwise material will
remain. Also make sure the circular pocket is not violated
mm
Solid machining
(only for G code)
• Complete machining
The circular pocket must be milled from a solid workpiece (e.g. casting).
• Post machining
A small pocket or hole has already been machined in the workpiece, which needs
to be enlarged. Parameters AZ, and ∅1 must be programmed.
FS Chamfer width for chamfering - (for chamfering only) mm
ZFS Insertion depth of tool tip (abs or inc) - (for chamfering only) mm
AZ
(only for G code)
Depth of premachining - (for remachining only) mm
∅1
(only for G code)
Diameter of premachining - (for remachining only) mm
* Unit of feedrate as programmed before the cycle call
