Features: This book comprehensively and systematically introduces the key contents of CNC technology: the hardware and software composition and characteristics of CNC systems, software algorithms for interpolation and tool compensation, the features and advantages of open-loop CNC systems; servo drive and position detection feedback technology, typical AC and DC closed-loop and semi-closed-loop servo systems, as well as concepts such as linear motor drive and digital servo systems; high-stiffness, low-friction, and gap-free precision mechanical technology in main drive and feed drive systems; the coordination of on/off control and CNC trajectory control completed by PC programmable controllers on CNC machines; basic methods and mathematical processing principles of CNC machining programming, as well as the overall trend of CNC technology toward systematization and integration, and the important supporting role of CNC technology in advanced manufacturing technology. This book can serve as a technical foundation course textbook for majors such as Mechanical Engineering and Automation, Mechanical Design, Manufacturing and Automation, and Mechatronics in higher education institutions, and can also be referenced by technical personnel engaged in CNC mechanical design, research, development, and application. Some technical data of servo drive and many mechanical system diagrams in the book are available for students' design reference; improved DDA interpolation and tool compensation algorithms, mathematical processing in CNC programming, and PC control technology are suitable for graduate students to select.
