【Abstract】 In this paper, an open numerical control gea r hobbing architecture based on digital signal processor (DSP) is presented. On th e basis of the programmable PID tuning, a filter of speed and acceleration feedf orward is provided to insure the static accuracy and dynamic performance of the system. Through a deep study on the principle of gear hobbing, an idea of electr onic differential gearbox is presented primarily, and the associated numerical c ontrol gear hobbing software is developed. The basic modules of the software for the motion control system are described. In the end, a successful instance on t he transformation of the YG3612 model gear hobbing machine tools using this nume rical control system is given.更多还原
