CNC区别于早期的NC，无论在控制性能还是在编辑操作方面，其功能都远远多于早期的NC。
CNC的主要功能：1. 承担加工程序的输入及编辑。
2. 能识别和运行多种国际上标准化的指令代码。
随着CNC的发展，这些加工指令代码越来越多。
3. 能提供高性能的进给控制功能。
4.人机对话相当方便。
5.能进行多机通讯及DNC 的加工。
6. 具备一定的故障诊断、反馈控制功能。
以上这些功能仅仅是CNC功能的主要部分。
随着现代是数控的发展，很多新的功能将不断增加及完善。
本设计主要是设计一个单片机CNC装置，要求能实现CNC的基本功能、位置控制及信号处理功能，为实现要求，分析系统应扩展一定容量的RAM、EPROM、实现三轴的进给运动、一个主轴控制，一定数量的辅助动作、一定数量的信息输入、一定量的按键及显示器。
【关键词】单片机、CNC、数控[Abstract]With the development of electronic technique, hardware numerical control system (NC) system developed greatly, experienced from NC to computer control system(CNC). Distinguish from the early stage of NC, no matter the control performance or edit operation, its function is farmore than the early NC.The main functions of CNC is : 1. Taking the input and editing of the programs. 2. The ability to analyze several kinds of international standardized instruction codes. With the developing of CNC, manufacturing codes are becoming more and more.3. Providing high-powered feed controlling function.4. Providing convenient man-machine conversation.5. The ability to conduct multi-machine communication and the process of DNC.6. The ability to diagnosis troubles and feedback controlling. The above are only the main functions of CNC.With the development of numerical control, there will be more and more new functions. This design for a single chip CNC equipment, can realize the basic function of the CNC control, position control, and signal processing function, to realize the requirement analysis, system should expand a certain capacity RAM, an EPROM, realize the three axis feeding movement, a spindle control, the number of auxiliary action, a certain amount of information input, a certain amount of buttons and display.
