Novel tool orientation optimization method based on a bunch of projection planes. The method could also be used broadening the scope of optimization using partitioning pdf determine the workpiece setup for general 3-axis machining.
The average strip width estimation method was presented as well. Quasi-feasible sectors containing the optimal tool orientation could be found according to the projection planes and the normal vectors of sample points. And the method can find the optimal tool orientation based on projection planes. A freeform surface was parted into 9 sub-surfaces firstly, and then the presented method was applied on those sub-surfaces to determine the optimal tool orientations.
