SINUMERIK 840D/840Di/810D Operation/Programming ShopMill (BAS) – 10.04 Edition
You can select the machining mode for milling the circumferential slot
as follows:
•
Roughing
During roughing, the individual planes of the slot are machined
one after the other from center point of the semicircle at the end of
the slot until depth Z1 is reached.
•
Finishing
In "Finishing" mode, the edge is always machined first until depth
Z1 is reached. The slot edge is approached on the quadrant,
which joins the radius. In the last infeed, the base is finished from
the center point of the semicircle to the end of the slot.
•
Edge finishing
Edge finishing is performed in the same way as finishing, except
that the last infeed (finish base) is omitted.
•
Chamfer
Chamfering involves edge breaking at the upper edge of the
circumferential slot.

With the "Alternat." softkey, you can position the circumferential slots
on a full circle or pitch circle.
