Contour Pocket Residual Material (Cycle63, Option) - Siemens SINUMERIK 840D sl Operating Manual

Programming technology functions (cycles)
8.5 Contour milling
Parameter Description
EW Note:
During insertion with oscillation, the message "Ramp path too short" will appear if the
tool is less than the milling cutter diameter away from the insertion point along the
ramp. If this occurs, please reduce the angle of insertion.
Lift mode Lift mode before new infeed
If the machining operation requires several points of insertion, the retraction height can
be programmed:
To retraction plane
•
Z0 + safety clearance
•
When making the transition to the next insertion point, the tool returns to this height. If
there are no elements larger than Z0 (X0) in the pocket area, then Z0 (X0) + safety
clearance can be programmed as the lift mode.
FS Chamfer width for chamfering - (only for chamfering machining)
ZFS Insertion depth of tool tip (abs or inc) - (for chamfering machining only)

Contour pocket residual material (CYCLE63, option)

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 changeover, 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 ShopTurn program, additionally appears when you press the "All parameters" softkey.
When programming, proceed as follows:
1. Contour pocket 1
2. Stock removal
3. Contour pocket 2
4. Stock removal
5. Contour pocket 1
6. Removing residual stock
7. Contour pocket 2
8. Removing residual stock
