Programming technology functions (cycles)
10.4 Milling
Parameter Description
FZ Depth infeed rate – (for vertical insertion only)
(only for Shop‐
Turn)
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.
● Post machining
The size of any existing smaller rectangular pocket or hole is increased in one or
more axes. You must program parameters AZ, W1 and L1 for this purpose.
AZ Depth of premachining – (for post machining only)
W1 Width of premachining – (for post machining only)
L1 Length of premachining – (for post machining only)
FS Chamfer width for chamfering - (for chamfering only)
ZFS Insertion depth of tool tip (abs or inc) – (for chamfering only)
