根据数控转塔冲床上料机构工作特点和要求，采用“PC+运动控制卡”模式构建了开放式数控系统平台，研究其在伺服控制系统中的应用。利用VS2008提供的MFC作为工具进行二次开发，开发底层控制程序。通过调用运动控制卡提供的运动函数库设计伺服控制系统软件。%This paper constructs the hardware of open type CNC system based on the mode of“PC+Motion Control Card”by using DMC1410 PCI motion control card and studies the use of hardware in the servo control system. The MFC provided VC++6.0 is used as a tool for secondary exploitation to develop the bottom control procedures. It designs the servo control system software through cal ing motion function library of motion control card.
