[QUOTE="esamuelr, post: 245339, member: 1477"] A 4 axis mill will allow for 2 insertion directions , but remember that a screw channel if defined in your cam can be considered an insertion direction. Often times the bridge or multi insertion direction unit will reuire use a 4 axis button for proper alignment in the machine along it's rotation axis. 5 axis machining makes it easier to do especially if there are significant angles covered in the a & b rotation axes of the machine. Any change in direction of a design is going to be limited by the maximum movement the machine can travel. Most 5 axis machining templates used in dental CAM don't employ undercut tools or strategies though. That is a whole different topic and conversation. [/QUOTE]
