Abstract
With the ever-increasing demands for machining accuracy and efficiency of complex parts in the high-end manufacturing industry, tool path planning has become a key link in numerical control (NC) machining, which directly affects the machining quality and production cost of parts. To improve the machining efficiency and surface quality of parts such as complex curved surfaces and thin-walled structures, this paper discusses the application of UG software in tool path planning. First, by utilizing the parametric modeling and machining modules of UG, a multi-strategy collaborative path generation scheme including contour layered machining, adaptive region segmentation and spiral cutting was designed for complex geometric features. Second, the genetic algorithm was integrated to optimize the tool path, so as to reduce non-cutting travel and abrupt steering. Finally, the feasibility and safety of the planned path were dynamically verified through the cutting simulation and collision detection functions of UG. By means of UG and knowledge fusion tools, intelligent algorithms are deeply integrated with the Computer-Aided Manufacturing (CAM) process, realizing the collaborative and autonomous optimization of tool paths and cutting parameters.
