• Machining direction:
When machining a pocket, a longitudinal slot, or a spigot, ShopMill
takes the machining direction (down-cut or up-cut) and the spindle
direction in the tool list into account. The pocket is then machined
in a clockwise or counterclockwise direction.
Climb milling
Conventional milling
Machining pockets in climb or conventional milling operation with CW spindle
rotation
During path milling, the programmed contour direction determines
the machining direction.
