| Abstract: | Detecting and removing gouges in the process of toolpath generation for machining free forms is an important phase. The modules of gouge removal are considered to be vital in any computer aided manufacturing (CAM) software. Instead of generating toolpaths and then searching interference positions, the process usually used, an approach is presented in which the surface is preprocessed in order to discard the zones of potential interference probability from the domain of definition of the surface. Afterwards, a simple sweeping process of the parametric space of the surface can generate interference-free toolpaths. This pre-processing approach has the advantage of eliminating interferences regardless of the orientation of the surface, and the chordal and scallop height tolerances for a given cutter. |
