Based on the basic theory of metal cutting and the surface forming theory of cutting workpiece, this book introduces the reasonable selection of tool geometric parameters and cutting parameters, as well as the causes and influencing factors of machining surface roughness. Taking the use and management of CNC tools as the main line, this paper expounds the characteristics and reasonable use technology of various CNC tools, practical tools for cutting typical materials, and the types and applications of CNC tool systems. In order to improve the machining efficiency of CNC machine tools and ensure the machining quality, this paper introduces the selection and management of tool setting instruments and the functions of tool management system. When editing, we should pay attention to simplifying the narrative of basic theory, paying attention to the connection with production practice and emphasizing the introduction of application content. Combined with the development trend of numerical control tool system, try to reflect the latest achievements of technical development and relevant international standards. The book is divided into 9 chapters: cutting basis of NC machining, machined surface quality, NC tool materials and their selection, types and characteristics of NC tools, NC turning tools, NC milling tools, hole machining tools, cutting performance of typical materials, practical tools and NC tool systems. It is systematic and comprehensive, integrating theory with practice.

This book is suitable for students in universities, technical secondary schools and vocational and technical colleges, as well as engineers engaged in CNC machining. It can be used not only as a teaching material, but also as a training book or technical reference book for personnel engaged in numerical control technology application, CAD/CAM technology application and mold design and manufacturing.

The competition of machinery manufacturing industry in 2 1 century is essentially the competition of numerical control technology, which is all-round. At present, with the rapid increase in the use of CNC machine tools in China, especially the adoption of new technologies such as high-rigidity integral casting lathe bed, high-speed CNC system and spindle dynamic balance, and the continuous development of tool materials, modern cutting is developing towards high-speed, high-precision and powerful cutting. The performance, quality and reliability of CNC machine tools and tool systems and the level of tool management system directly affect the production efficiency and processing quality of millions of expensive CNC machine tools in China's manufacturing industry, and also directly affect the production technology level and economic benefits of the whole machinery manufacturing industry. It can be said that the level of NC tool and its management system is becoming a "bottleneck" restricting the manufacturing efficiency of NC machine tools in China. If a worker wants to do a good job, he must sharpen his tools first. This book is written after repeated practice and summary on the basis of collecting a large number of latest technological development achievements at home and abroad.

The tool, tool system and tool management system of CNC machine tools are the basis of exerting machining efficiency and ensuring machining quality. Only advanced CNC machine tools, without advanced tools, tool systems and tool management systems, or without mastering the rational use technology of tools, the effectiveness of CNC machine tools cannot be fully exerted. Based on the basic theory of cutting, this book aims at mastering the rational use technology of CNC machine tools and giving full play to the efficiency of CNC machine tools. On the basis of introducing the cutting basis of NC machining, the causes of surface roughness, the types and selection principles of tool materials, the characteristics, failure forms and reliability of NC tools, this book analyzes the types, characteristics and reasonable use technologies of NC turning tools, NC milling tools and hole machining tools, and gives typical materials. At the same time, combined with the latest development achievements of CNC tool system at home and abroad, the knowledge and related standards of CNC tool system, tool presetting instrument and tool management system are introduced. The book is comprehensive and closely related to production practice.

This book is suitable for students in universities, technical secondary schools and vocational and technical colleges, as well as engineering and technical personnel engaged in NC machining practice and research. It can also be used as training materials or technical reference books for personnel engaged in numerical control technology, CAD/CAM technology application and mold design and manufacturing.

Chapters 2-7 and 9 of this book were written by Xu Honghai of north china university of technology, and chapters 1 and 8 were written by Wang Ben of Shougang Institute of Technology. North china university of technology Zhang provided a lot of technical information for the compilation of this book. Xu Honghai is responsible for the compilation and finalization of the book.

In the process of writing this book, I got strong support and help from leaders and colleagues in north china university of technology. Professor Yu Hua of Graduate School of Chinese Academy of Sciences and General Manager wang hong of Chengdu Inge CNC Tool & Mould Co., Ltd. have put forward many valuable opinions and provided rich materials for the writing of this book, and I would like to express my gratitude here.

Due to the limited level of editors, coupled with the rapid development of CNC tools, tool systems and tool management systems, this book inevitably has shortcomings. I hope that readers and colleagues will put forward valuable opinions.
