Application of Multi-Contour Cutting in Algorithms for Solving the Cutting Path Problem

The cutting path problem for CNC sheet metal equipment is considered in this article. method of multi-contour application described solving Cutting Path Problem (CPP). to be combine contours «blocks» (groups) and several performed by using special techniques (common cut, «chained» cutting) order reduce values tool length number piercings compared with standard technique (where only idle minimized) article presents results computing experiments proposed (multi-contour common cut) algorithm CCP-Relax (in which the used). examples testing are instances from Library CPPLib.
