摘要
针对电火花数控系统硬件平台集成度较低、可扩展与兼容性差和多轴控制实时性能有待提高等问题,课题组采用实时性能良好的EtherCAT协议,设计开发了基于“ARM+FPAG+ECM-XF”的嵌入式电火花加工机床数控(Computer Numerical Control,CNC)系统硬件平台,并基于下位机现场可编程门阵列(Field Programmable Gate Array,FPGA)与ECM-XF芯片建立数控系统EtherCAT主站,实现多轴精确控制。该平台上、下位机主控板的设计均采用了核心板+底板的方式,极大提高了硬件平台的可拓展性与移植灵活性,便于维护。实验结果表明:该数控系统硬件平台可以较好地完成电火花小孔加工和圆弧铣削,上、下位机能充分发挥各自优势,任务分配合理,开发升级成本低,系统集成度高,实时性与稳定性良好,具有一定的实用价值。
Aiming at the problems of low hardware integration,poor expandability and compatibility,and insufficient real-time performance of the hardware platform of the Electrical Discharge Machining(EDM)Computer Numerical Control(CNC)system,the research team adopted the EtherCAT protocol with excellent real-time performance and developed an embedded EDM machine tool CNC system hardware platform based on the"ARM+FPGA+ECM-XF"architecture.The platform established an EtherCAT master station of CNC system on the lower-level Field Programmable Gate Array(FPGA)and ECM-XF chip to achieve precise control of multi-axis.The design of both the upper-level and lower-level main control boards adopted the core board+baseboard method,greatly improving the expandability of platform and flexibility for porting,and facilitating maintenance.The experimental results show that the CNC system hardware platform can complete well in EDM small-hole processing and circular milling,and the upper-level and lower-level systems can fully utilize their respective advantages,with reasonable task division and low development and upgrading cost.The system has high integration,good real-time performance and stability,and certain practical value.
