【Abstract】 With the acceleration and deceleration circuit of CNC machine tools as our subject, an efficient approach is proposed for generating velocity profiles that cannot be generated by previous techniques. Based on the proposed approach, an acceleration and deceleration circuit for CNC machine tools is designed by using the VHDL and it is implemented with a FPGA. A velocity profile generated by the acceleration and deceleration circuit will be applied to one single-axis control system. It will have a bright future for its application.更多还原
