Abstract
In 3+2 axis NC machining, only three linear axes are executed while 5-axis machine’s two rotational axes are locked. Compared with conventional 3-axis machining, the main advantage of 3+2 machining is that it allows use of a shorter cutter. The magnitude of tool deflection and the stability of cutting process strongly depend on the slenderness of the tool. However, the tool overhang length can’t be easily shortened because of collision avoidance. In this paper the accessibility cone of a milling cutter is newly defined to generate collision-free cutting orientations. The accessibility cone and safe tool length can be efficiently computed by a novel method using graphics hardware. The proper cutting orientation of 3+2 machining is then obtained by optimizing the safe and shortest tool length. The computational example and cutting experiment of sculptured surface machining confirm the validity of the approach.
