day-to-day "NC", in essence, is that "computer numerically controlled."
还要指出的是，虽然国外早已改称为计算机数控（即CNC）了，而我国仍习惯称数控（NC）。所以我们日常讲的"数控"，实质上已是指"计算机数控"了。
1.3, the trend of future development of NC
1.3、数控未来发展的趋势
1.3.1 continue to open, the sixth generation of PC-based development
1.3.1 继续向开放式、基于PC的第六代方向发展
Based on the PC with the open, low-cost, high reliability, rich in resources such as hardware and software features, and more CNC system manufacturers will embark on this path. At least it used PC as a front-end machine, to deal with the human-machine interface, programming, networking and communications problems, the former NC Some systems have the mandate. PC machine with the friendly interface, will be universal to all CNC system. Remote communications, remote diagnostics and maintenance will be more widespread.
基于PC所具有的开放性、低成本、高可靠性、软硬件资源丰富等特点，更多的数控系统生产厂家会走上这条道路。至少采用PC机作为它的前端机，来处理人机界面、编程、联网通信等问题，由原有的系统承担数控的任务。PC机所具有的友好的人机界面，将普及到所有的数控系统。远程通讯，远程诊断和维修将更加普遍。
1.3.2 high-speed and high-precision Development
1.3.2向高速化和高精度化发展
This is to adapt to high-speed and high-precision machine tools to the needs of the development direction.
这是适应机床向高速和高精度方向发展的需要。
1.3.3 intelligent direction to the development
