Abstract. Approaches to the problem of optimization of executive tool trajectory in CNC equipment used for laser treatment of complex-shaped surfaces are considered. Time of processing is used as the main optimization criteria. Two principal time shortening methods are proposed — by increasing in processing speed using smooth aliasing of acceleration/deceleration curves, and by minimizing the quantity of auxiliary passes. A genetic algorithm with crossover (similar to the one used to solve the traveling salesman problem) is proposed to reduce the number of auxiliary paths
Keywords: CNC tool, trajectory optimization, laser processing, genetic algorithms, traveling salesman problem, hi-speed processing
