| In order to improve the processing accuracy, stability and efficiency of CNC keyhole machine, an ARM Cortex M7 core based embedded control system was proposed. The human computer interaction module was designed with regular expressions decoding method; the servo motor drive module was designed based on the seven stage flexible S shaped acceleration and deceleration control algorithm; the MCU main control module, the interface circuit module and the power management module of the whole system were designed, and the corresponding control application software were designed according to the functional requirements of each module. The testing and verification results show that the control system is simple to operate and realizes fast and stable accurate processing, improving production efficiency and processing quality, and reduces processing costs. The system can realize automatic production of CNC keyhole machine. |
