Abstract

Abstract: In the machining process of large-scale complex curved surface, workers will encounter problems such as empty stroke of tool, collision interference, and overcut or undercut of the workpieces. This paper presents a method for generating the optimized tool path, compiling and checking the numerical control (NC) program. Taking the bogie frame as an example, the tool paths of all machining surface are optimized by the dynamic programming algorithm, Creo software is utilized to compile the optimized computerized numerical control (CNC) machining program, and VERICUT software is employed to simulate the machining process, optimize the amount of cutting and inspect the machining quality. The method saves the machining time, guarantees the correctness of NC program, and the overall machining efficiency is improved. The method lays a good theoretical and practical foundation for integration of the similar platform.
