Circular Pocket (Pocket4) - Siemens SINUMERIK 840D sl Operating Manual

Parameter Description
FZ Depth infeed rate – (for vertical insertion only)
(only for ShopMill)
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 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
•
A rectangular pocket or hole has already been machined in the workpiece. This
needs to be enlarged in one or 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 chamfer only)
* Unit of feedrate as programmed before the cycle call

Circular pocket (POCKET4)

Function
You can mill any circular pocket with the "Circular pocket" cycle.
The following machining methods are available:
● Mill circular pocket from solid material.
● Predrill circular pocket in the center first if, for example, the milling cutter does not cut in
● Machine pre-machined circular pocket (see "Solid machining" parameter).
The following machining types are available for milling using the "Circular pocket" function:
● Plane-by-plane
● Helical
