摘　　要：数控系统是保证数控机床加工精度的关键所在。根据线切割机床的加工特点和要求,采用模块化设计思想,设计开发了一种基于Windows操作系统的快走丝线切割机床数控系统。系统以工业计算机和多轴运动控制器为硬件控制核心、实现了上位机(工控机)和下位机(运动控制器)的可靠通信及机床工作台运动控制,并以VB6.0为软件开发环境设计了友好的人机交互操作界面。该系统具有全绘图式编程、短路自动回退、自动切割等多种功能,通过适当的参数设置,可对工件进行自动多次切割。经过实验验证表明,开发的数控系统能够较好地满足机床对加工精度和加工质量的要求,具有广泛的市场前景和较高的应用价值。The numerical control system is the key to ensure the accuracy of the numerical control machine.According to the specialty and demand of wired electric discharge machining（WEDM）,a WEDM-CNC system in which the IPC and MPC2810 are used for the control core based on Windows is studied and developed using module structures.It can realize communication between IPC and microcontroller.A friendly human-computer interaction interface is developed using VB6.0.The CNC system have going back when in shortage of circuit.Auto cutting and multi-cutting function can also be realized automatically by setting proper parameters.It is showed that the developed CNC system can better meet the requirements of cutting accuracy and quality for WEDM.Therefore it has a broad market prospect and high application value.
