Optimization of cutter-location for 5-axis NC machining freeform surface with a fat-end cutter

摘要

5-axis NC machining freeform surface with a flat-end cutter can theoretically improve material-removal rate and surface finish, but it is very difficult to generate a gouge-free cutter location. A new method of generating optimal cutter path is proposed to define the effective radius of a flat-end cutter and determine the optimal step-forward distance and step-over distance. Thereby improving the NC machining efficiency and quality of freeform surfaces.
