Optimization of CNC isoscallop free form surface machining using a genetic algorithm

Isoscallop machining with edge-based master cutter path (MCP) essentially ensures uniformity of surface roughness over entire surface of part but may not necessarily ensure minimization of machining time. In the present work, it has been shown that there is a provision for minimizing machining time while implementing Isoscallop machining, by optimizing the orientation of the primary or Master Cutter path (MCP) through application of a GA. The results indicate a substantial reduction in total machining time for the proposed approach compared to those obtained through previously reported cutter path generation strategies.
