Residual Material Contour Pocket (Cycle63) - Siemens SINUMERIK 840D SL Operating Manual

Parameter Description
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)
Lift mode Lift mode before new infeed - (only for ∇, ∇∇∇ base or ∇∇∇ edge)
If the machining operation requires several points of insertion, the retraction height to
which the tool is retracted, is selected as follows:
To retraction plane
•
Z0 + safety clearance
•
If there are no elements larger than Z0 in the pocket area, "Z0 + safety clearance" can
be selected as the lift mode.
FS Chamfer width for chamfering - (only for chamfering machining)
ZFS Insertion depth of tool tip (abs or inc) - (for machining only)
* Unit of feedrate as programmed before the cycle call
Note
When input manually, the starting point can also be located outside the pocket. This can be
useful, for example, when machining a pocket which is open on one side. The machining
operation then begins without insertion with a linear movement into the open side of the
pocket.

Residual material contour pocket (CYCLE63)

Function
When you have removed stock from a pocket (with/without islands) and there is residual
material, then this is automatically detected. You can use a suitable tool to remove this
residual material without having to machine the whole pocket again, i.e. avoiding
unnecessary non-productive motion. Material that remains as part of the finishing allowance
is not residual material.
The residual material is calculated on the basis of the milling cutter used for stock removal.
If you mill several pockets and want to avoid unnecessary tool changes, remove stock from
all the pockets first and then remove the residual material. In this case, for removing the
residual material, you also have to enter a value for the reference tool TR parameter, which,
for the ShopMill program, additionally appears when you press the "All parameters" softkey.
When programming, you must then proceed as follows:
1. Contour pocket 1
2. Solid machining
3. Contour pocket 2
4. Solid machining
5. Contour pocket 1
