Programming technology functions (cycles)
8.4 Milling
Parameter Description
Clamp/release spindle (only for end face C/peripheral surface C, if inserted vertically)
The function must be set up by the machine manufacturer.
(only for
ShopTurn)
FZ Depth infeed rate – (for vertical insertion only)
(only for G code)
FZ Depth infeed rate – (for vertical insertion only)
(only for
ShopTurn)
EP Maximum pitch of helix – (for helical insertion only)
ER Radius of helix – (for helical insertion only)
The radius cannot be any larger than the milling cutter radius; otherwise, material will
remain.
EW Maximum insertion angle – (for insertion with oscillation only)
Solid machining
Complete machining

(for roughing only)
The rectangular pocket is milled from the solid material.
Remachining

The size of any existing smaller rectangular pocket or hole is increased in several
axes. You must program parameters AZ, W1 and L1 for this purpose.
AZ Depth of premachining – (for remachining only)
W1 Width of premachining – (for remachining only)
L1 Length of premachining – (for remachining only)
FS Chamfer width for chamfering - (for chamfering only)
ZFS Insertion depth of tool tip (abs or inc) – (for chamfering only)
* Unit of feedrate as programmed before the cycle call

Circular pocket (POCKET4)

Function
You can use the "Circular pocket" cycle to mill circular pockets on the face or peripheral
surface.
The following machining variants are available:
● Mill circular pocket from solid material.
● Pre-drill circular pocket in the center first if, for example, the milling cutter does not cut in
For milling with the "Circular pocket" function two methods are available: the plane-by-plane
method and the helical method.
394
the center (program the drilling, circular pocket and position program blocks in
succession).
