The field of tool engineering and die design, a complex and fascinating subject, continues to advance rapidly. This broad and challenging topic continues to incorporate new concepts at an increasing rate, making tool and die design a dynamic and exciting field of study. In preparing this third edition, my most important goal has been to provide a comprehensive state-of-the-art textbook on die design fundamentals, which also encompasses the additional aims of motivating and challenging students.
This new edition provides balanced coverage of relevant fundamentals and real-world practices so that the student can understand the important and often complex interrelationships between die design and the economic factors involved in manufacturing sheet metal-forming products.
A groundbreaking and comprehensive reference with many thousands of copies sold since it first debuted in 1962 as J.R. Paquin’s Die Design Fundamentals, this new third edition of Die Design Fundamentals basically follows the same design philosophy: It is a step-by-step introduction to the design of stamping dies. However, the original book has been completely revised and updated, and the order of the chapters has been changed to follow the logical process of designing a die.
The plan of the book remains unique. After introductory material and a discussion of 20 types of dies, the design of a representative die is separated into 14 distinct steps. Each step is illustrated in two ways: first, as a portion of an engineering drawing, that is, as the component is actually drawn on the design; second, the die design is shown pictorially in order to improve the user’s visualization. In successive sections of the book, each step is detailed as it is applied to the design of the various types of dies listed in
