Programming technological functions (cycles)
10.2 Milling
Parameter Description
FZ Depth infeed rate – (only for insertion and vertical insertion)
(only for ShopMill)
EP Maximum pitch of helix - (for helical insertion only)
The helix pitch may be lower due to the geometrical situation.
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
Solid machining
● 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. This
needs to be enlarged. Parameters AZ, and ∅1 must be programmed.
FS Chamfer width for chamfering - (for chamfering only)
ZFS Insertion depth of tool tip (abs or inc) - (for chamfering only)
AZ Depth of premachining - (for remachining only)
∅1 Diameter of premachining - (for remachining only)
