摘　　要：设计一款人机界面-ARM微处理器的运动控制芯片数控系统.它包括监控、运动控制和驱动3个部分,能够实现直线插补、圆弧插补、位模式插补和连续插补等功能,结合各种类型插补可以加工对精度要求较高的产品.系统采用触摸屏和ARM芯片取代传统的PC机,实现人机交流和控制信息传送,MCX314AS相当于取代PC_BASED数控系统的运动控制卡,从而简化系统结构,降低成本.此外,运行结果表明,系统具有较高的稳定性和可靠性.This paper presents a numeric control system based on human machine interface（HMI）,ARM and motion control chip.The system consists of three parts,such as monitoring,motion controlling and driving.And with those function parts,it can accomplish linear interpolation,circular interpolation,bit pattern interpolation and continuous interpolation,etc..It also can process high-precision products by combining all types of interpolation.Moreover,by using touch screen and ARM instead of traditional PC,in other words,using MCX314AS instead of PC_BASED motion control chip,its structure and cost are improved,it can also implement human-machine communication and control information transfer.The operating results show a higher stability and reliability.
