摘　　要：针对目前DNC系统中计算机与NC机床通信中存在的问题,将CAN总线引入到DNC系统之中,分析和讨论了其硬件构成和网络拓扑结构,以VC++6.0为开发工具,应用专用编译工具Lex&Yacc、三维图形标准库OpenGL和数据库Access,并基于Windows多任务、多线程技术,对其软件系统进行了开发,最终构建了基于CAN总线DNC实用系统.Aim at the communication problems of computer and NC machine tool in DNC system, the CAN fieldbus is introduced into the DNC system. The hardware constitution and its network topological structure of the system are analyzed and discussed. Using VC＋＋ 6.0 as development tool assisted with special compiling tools LEX＆YACC, 3D standard graphic library OpenGL and data base Access, and based on the multi-task and muhi-thread technologies, the system software fieldbus is established.
