基于EtherCAT通信协议的电火花加工数控系统硬件设计
Hardware Design of EDM CNC System Based on EtherCAT Communication Protocol
摘要
Abstract
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.关键词
