Features: This book is divided into six chapters. Chapter 1 introduces common electrical components used in machine tools and their selection, the basic elements of relay control circuits in machine tools, the analysis and design methods of typical machine tool relay control systems, and maintenance of machine tools. Chapter 2 covers DC motor speed control systems, introducing the concepts, indicators, and methods of speed control, the role of negative feedback, the composition and characteristics of single-loop DC speed control systems with and without static error, and a brief introduction to speed-current dual-loop systems and reversible systems. Chapter 3 discusses AC motor speed control systems, introducing cascade speed control for asynchronous machines and slip ring speed control, with a focus on the principles of frequency conversion speed control, common frequency converters, and their engineering applications. Chapter 4 primarily introduces the principles and applications of Programmable Logic Controllers (PLCs), emphasizing the programming components and instruction systems of the F1 series PLCs, providing a brief overview of C series PLCs, and offering multiple application examples. Chapter 5 covers numerical control machine tools, introducing their features, working principles, and development trends, as well as the position detection and servo components of CNC machine tools, the basics of CNC programming, and maintenance. Chapter 6 lists four experimental topics for selection and use. This book can serve as a textbook for mechanical engineering programs in higher vocational colleges and technical colleges, or as a teaching material for adult universities, radio and television universities, and related disciplines. It can also be used as a reference for engineering technicians.
