| Abstract: | The NC control model and real-time interpolation algorithm of polygon non-circular surface were studied deeply and systematically. A motion control model for machining polygon surfacs was set up, and the real-time interpolation algorithm was presented based on central angle division. The problems of tool path generation were solved successfully, and a feedrate self-turning method was presented to uniform the machining speed on the basis of curvatures of the section. The foundation is laid for machining processes and applications of polygon non-circular surfaces. |
