摘　　要：短电弧机床加工过程中的加工电流设定和位置进给控制,必须根据其工作方式和刀具电极损耗情况进行动态的补偿调整,才能更好地保证被加工工件的加工效率和加工精度。为研究短电弧机床数控系统,设计用于位置进给控制和加工电流设定与检测的运动控制器,并结合USB通讯技术介绍如何实现运动控制器核心处理DSP芯片与USB接口的数据传输。In order to guarantee the machining efficiency and accuracy, the working current setting and feed motion control of short electric arc NC machine should be compensated and adjusted dynamically according to operation status and electrode dissipation. With the standpoint of designing an NC controller for the short dectric arc NC machine to perform mechanics research, an overall design scheme of the motion controller for feed motion control, working current setting and detection is given. And finally, combining with USB communication technology, gives an introduction to the realization of the data transmission between kernel processing chip DSP of the motion controller and USB interface.
