Abstract:
A regional optimization of automatically generated machining toolpath for computer based freeform mechanical models is considered in the framework of multi-axis (three to five) machining operations. Consider a trichotomy of an arbitrary freeform shaped surface into convex, concave and saddle-like regions. Saddle-like and concave regions can be milled using a ball end tool, in a 3- or a 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. 1
