Based on the product positioning of "based on professionalism and practicality first", Metal Processing Magazine has focused on planning three series of books: taboo series, practical series, and selection series. The book "Taboos in the Application of CNC Tools" is a typical representative of the "Taboo Series" books and has been published in March 2023. The book lasted 4 years and used a crowdfunding model to compile a total of 276 taboo cases around common problems in the applications of turning tools, drilling tools, milling tools, boring tools, threading tools, cutting and grooving tools, and grinding tools. .
(This case is selected from Chapter 1 Taboos of Application of Turning Tools in "CNC Tool Application Taboos", written by Fan Cunhui of Zhengzhou Aircraft Equipment Co., Ltd.)
Turning tool application taboos
Contraindications for turning tools using precipitation hardened stainless steel materials
The material characteristics of precipitation hardened stainless steel after solid solution and aging treatment are: high strength, good toughness, and corrosion resistance. It is a commonly used material for parts in the aviation field in recent years. However, its material characteristics make it severely work-hardened, causing large cutting forces and cutting problems. When the temperature is high, the workpiece is prone to thermal deformation, which leads to difficulty in chip breaking and obvious sticking of the workpiece. The tool is prone to rapid wear and tear, making cutting difficult to break and easy to bond, making processing more difficult.
In order to ensure efficient cutting of this type of material, it is necessary to correctly select cutting tools and reasonably select cutting parameters. The specific selection taboos are as follows.

Details description
This book first takes processing types, processing materials, tool configurations, tool materials and processing performance as the starting point, and based on tool applications, process applications, processing objects and other taboos, it comprehensively and in detail explains turning tools (Part 1 Chapter), drilling tools (Chapter 2), milling tools (Chapter 3), boring tools (Chapter 4) and threading tools (Chapter 5), parting and grooving tools (Chapter 6) may be encountered problems and solutions, down to the smallest detail. Secondly, the number of taboos and solutions in the application of grinding tools (Chapter 7), CNC tool selection (Chapter 8), and CNC tool clamping (Chapter 9) are discussed. Finally, CNC tool programming taboos are introduced (Chapter 10).
In terms of CNC machining, especially in the practical application of cutting tools, this book can provide experience and reference for many process technicians, on-site managers, tool purchasers, etc. who are engaged in mechanical processing; in terms of cutting tool R&D and design, this book can provide tool manufacturers with user experience. Demand feedback; it can also be used as a reference book for teachers and students of mechanical majors to improve their mechanical processing technology level.
