Features: This book is a carefully compiled collection of competition questions from the first National CNC Competition and provincial CNC selection competitions. The book is divided into 7 chapters: Chapter 1 selects theoretical knowledge questions from CNC skill competitions, Chapter 2 selects CNC lathe skill competition questions, Chapter 3 selects CNC milling machine skill competition questions, Chapter 4 selects machining center skill competition questions, Chapter 5 selects CAD skill competition questions, Chapter 6 selects CAE skill competition questions, and Chapter 7 selects 3D modeling images of CNC competition questions. The theoretical knowledge competition questions in the book are accompanied by detailed reference answers. All skill competition operation questions include process analysis, cutting tools, fixtures (including positioning and clamping schemes), selection of cutting process parameters, node and base point numerical calculations, complete process routes, and program descriptions. The book adopts a one-question-multiple-solutions approach, using the three typical systems with the largest market share in China—FANUC, SIEMENS, and Zhonghua—as reference program answers. The CAD/CAM competition questions use the comprehensive Unigraphics software as the reference software. This book is particularly suitable for highly skilled CNC professionals and can serve as the examination textbook for national vocational skill level assessments, including CNC senior technicians, CNC technicians, and advanced CNC technicians. It can also be used as a teaching reference for instructors in major vocational colleges and universities majoring in CNC and related fields, as well as a reference book for a wide range of engineering technicians in factories and enterprises specializing in CNC machining and CNC software development.
