SINUMERIK 840D sl Operation/Programming ShopTurn (BAT) – 08/2005 Edition
When you want to mill a contour on the peripheral surface ("peripheral
surface/peripheral surface C" machining plane), you can work with or
without a slot wall offset.

Slot wall offset Off
ShopTurn creates slots with parallel walls when the tool diameter is
equal to the slot width.
If the slot width is larger than the tool diameter, the slot walls will
not be parallel.

Slot wall offset On
ShopTurn creates slots with parallel walls also when the slot width
is larger than the tool diameter.
If you want to work with a slot wall offset, you must not program the
contour of the slot, but instead the imagined center path of a bolt
inserted in the slot whereby the bolt touches both walls. The
parameter D is used to specify the slot width.
Press the "Milling", "Contour milling" and "Path milling" soft keys.
