摘要：

A regional optimization of automatically generated machining toolpaths for computer based freeform mechanical models is considered in the framework of multiaxis (3-5) machining operations. A trichotomy of an arbitrary freeform shaped surface into convex, concave and saddle-like regions is considered. Saddle-like and concave regions can be milled using a ball end tool, in 3-axis or 5-axis mode. A subset of the convex regions can be machined faster and with a smaller scallop using a flat end tool that is aligned with the normal of the surface in 5-axis mode. A method to robustly detect and eliminate local gouging of the milling tool into the object is developed and demonstrated on an actual part.
