"基于西门子802C数控系统设计项目指导书：伺服控制与电气原理图详解"。

With the continuous progress of science and technology and the development of social productivity, excellent manufacturing technology based on numerical control technology is gradually replacing traditional mechanical manufacturing technology at a faster pace, which has become the current trend of mechanical manufacturing technology development. Numerical control machine tools are widely used in the manufacturing industry, leading to an increasing demand for talents who are proficient in operating, programming, and maintaining numerical control machine tools. Over the years, various universities have opened numerical control majors, reflecting the demand for such talents in society from an educational perspective. However, this also raises the issue of how to cultivate talents who can adapt to engineering applications in numerical control teaching. This project is based on the Siemens SINUMERIK 802C numerical control lathe control system design. After understanding and mastering the structure, working principle, and control methods of the Siemens 802C numerical control system, the project configured the servo system, spindle control system, and auxiliary motion control system based on it. By consulting relevant materials, the hardware of the numerical control lathe was selected, the working principles of each module were understood, and external hardware circuits were designed. The project ultimately designed a system that can achieve functions such as spindle control, feed motion control, and auxiliary device control. Through research, the project gained an understanding of the characteristics of the Siemens 802C numerical control system's built-in PLC and designed an automatic turret PLC control program. In addition, critical parameters of the numerical control system were set. The project keywords include Siemens 802C, servo system, spindle control system, and electrical schematics.
