Numerical control machining optimization system and method based on physical simulation

Abstract

A numerical control machining optimization system and method based on physical simulation is provided. The system comprises an input module, a code parsing and geometric simulation module, a physicalsimulation module, an optimization module and an output module that are successively connected, and a cutting force model database module connected to the physical simulation module. The input moduletransmits a read numerical control path file and physical information to the code parsing and geometric simulation module. The code parsing and geometric simulation module transfers specific parameterinformation of a full process cycle determined through parsing and simulation to the physical simulation module. The physical simulation module calculates a cutting force according to the parameter information by combining with a cutting force coefficient in the cutting force coefficient model database module, and transmits the cutting force to the optimization module. The optimization module generates a new machining code through an optimization process, and transmits the new machining code to the output module. The output module converts the new machining code into a numerical control codethat can be directly read by a machine tool, and outputs the numerical control code. According to the numerical control machining optimization system and method based on physical simulation, machiningefficiency is improved, and tool abrasion is reduced.
