| 针对桌面式电火花加工机床数控系统的兼容性和加工放电要求，课题组设计了一款基于ARM和现场可编辑门阵列（field programmable gate array，FPGA）的电火花加工机床数控系统硬件平台。该平台任务分配均匀合理，以ARM处理器为核心搭建上位机，移植Linux系统进行多任务处理、人机界面、插补运算等任务；以FPGA为核心搭建的下位机系统负责运动控制、放电脉冲控制、辅助模块控制等任务；硬件平台的搭建采用了核心板+基板的方式并采用以太网口进行通信。试验结果表明该硬件平台搭建的数控系统可以较好地完成电火花小孔加工。该研究提供了一种移植性好、迭代升级成本低、适配多种脉冲电源的电火花加工机床数控系统硬件平台设计方案。 |

| Aiming at the compatibility and discharge requirements of desktop EDM machine tool numerical control system, a hardware platform of EDM machine tool numerical control system based on ARM and FPGA was designed. The task distribution of the platform was uniform and reasonable, with ARM as the core to build the upper computer, and the transplantation of Linux system to carry out multi task processing, man machine interface and interpolation operation. The lower computer system based on FPGA was responsible for motion control, discharge pulse control, auxiliary module control and other tasks. The hardware platform was built in the form of core board plus base board and the communication was carried out by Ethernet port. The experimental results show that the CNC system built by the hardware platform can accomplish the EDM small hole machining. This research provides a hardware platform design of EDM machine tool numerical control system with good portability, low cost of iterative upgrade and adaptability to various pulse power sources. |
