数控机床的大量普及,在国际上是在七十年代初期,即在微处理器应用到数控系统。使系统功能有了跃进,价格显著下降之后。八十代以来,技术进步的速度加快,产品更新的周期缩短,对加工设备的柔性化要求也日益增长。图1为1970年以来各主要工业国家数控机床的发展情况。数控机床的 The popularity of CNC machine tools in the international community in the early seventies, that is, the application of the microprocessor to the numerical control system. The system has made a leap forward, after the price dropped significantly. Since the 1980s, the speed of technical progress has been accelerated, the cycle of product renewal has been shortened, and the requirements for the flexibility of processing equipment have also been increasing. Figure 1 shows the development of CNC machine tools in major industrial countries since 1970. CNC machine tools
