This book systematically discusses the latest design theory and design methods of cam mechanisms , covering the calculation , selection , design , manufacturing and testing of cam mechanisms . In the theoretical research , this book lays the foundation for the cam calculation theory based on vector mathematics and dimensionless motion laws , provides the source program of vector mathematical plane trigonometric solution , gives the design and calculation framework of various cams , so that readers can conduct in - depth research and programming ; in the design method , in addition to the classic design methods , this book also introduces virtual prototype design , three - dimensional modeling and motion simulation technology ; in the practical application , this book specially compiles the common problems of cam mechanisms and illustrations , so that readers can learn and refer to . This book is classic , rich , practical , theoretical and practical , with pictures and text , step by step , from shallow to deep , easy to learn . Its systematic , theoretical , advanced , scientific , practical , simple and book - like characteristics are of great guiding significance and practical value for the design , manufacturing and testing of automatic machine cam mechanisms . This book can be used by engineering and technical personnel in research institutes and enterprises , and as a reference book for teachers and students of relevant majors in colleges and universities .
