| Abstract: | To satisfy the requirements of precision and speed for large-size laser machining,a CNC system based on the DSP,FPGA and microcontroller is developed.Microcontroller is used to control the human-computer interface,DSP is used to process the data,and FPGA is used to output the machining signal.The hardware mentioned above ensures the capabilities of high-speed and precision of machining.In addition,the data are saved in flash memory that makes the machine work offline.By optimizing the design of software and hardware,the system reaches the design goals,and satisfying machining effects are obtained. |
