An approach of tool paths generation for CNC machining based on CUDA

This paper presents a new tool paths generation method for CNC machining based on GPU-CPU fusion calculation. CUDA, a general purpose parallel computing architecture, was provided by NVidia to resolve problems of mass data parallel computing. The new tool paths generation algorithm based on isoparametric method was redesigned to use CUDA. The final comparison experiment tests the running performance of the conventional isoparametric method and new improved method. Results of experiment show that the improved method based on CUDA can significantly improve running efficiency of tool paths generation method.
