Features: The book "Principles of CNC" is divided into eight chapters. Chapter Conclusion, which introduces the basic concepts of digital control, the fundamental composition and classification of CNC systems, the relevant regulations of CNC machine tools, and the development of CNC technology. Chapter 2: Sensors and Input Channels, which discusses the position and speed sensors commonly used in CNC machine tools, measurement circuits, and their signal connections with CNC systems. Chapter 3: Servo Systems of CNC Machine Tools, which covers open-loop servo systems, DC and AC speed control systems, phase-locked servo systems, and closed-loop position control systems. Chapter 4: Interpolation Principles and Data Processing of CNC Systems, which introduces common trajectory control methods in CNC systems, user program decoding, and tool compensation calculation methods. Chapter 5: Human-Machine Interface and Communication Interface, which explains the working principles of common human-machine interfaces (e.g., keyboards, LED digital displays, CRT displays, tape readers) and the principles of common communication interfaces (e.g., RS232C, current loop, MAP). Chapter 6: Programmable Controllers of CNC Machine Tools, which covers the basic principles, programming, and control examples of programmable controllers commonly used in CNC machine tools. Chapter 7: Economic CNC Systems, which discusses the design methods and examples of open-loop CNC systems. Chapter 8: Standard CNC Systems, which introduces the overall structure, hardware structure, and software structure of common standard CNC systems. The book is easy to understand yet comprehensive, with a well-balanced depth of content. It emphasizes both advanced concepts and practicality, combining theory with examples. It provides a systematic overview while delving into details for practical application, making it a highly practical and versatile textbook. This book is intended for the CNC technology training of junior and intermediate CNC technicians. It can also serve as a textbook for college, vocational school, and technical school students in CNC technology applications, CNC machine tool processing, mechanical manufacturing, and mechatronics. Additionally, it can be used as a reference for engineering technicians working in CNC machine tools.
