By an engineer with decades of practical manufacturing experience, this book is a complete modern guide to sheet metal forming processes and die design - still the most commonly used methodology for the mass-production manufacture of aircraft, automobiles, and complex high-precision parts. It illustrates several different approaches to this intricate field by taking the reader through the "hows" and "whys" of product analysis, as well as the techniques for blanking, punching, bending, deep drawing, stretching, material economy, strip design, movement of metal during stamping, and tooling. While concentrating on simple, applicable engineering methods rather than complex numerical techniques, this practical reference makes it easier for readers to understand the subject by using numerous illustrations, tables, and charts. Emphasizes the influence of materials as an aid to understanding manufacturing processes and operations. Features the essential mathematical formulas and calculations needed for various die operations and performance evaluation. Shows the comparative advantages and liabilities for each manufacturing process and operation. Offers a complete picture of the knowledge and skills needed for the effective design of dies for sheet-metal forming processes highlighted with illustrative examples. Provides properties and typical applications of selected tool and die materials for various die parts.

Sheet Metal Technology is written in Dave’s unique style with the beginner or vocational student in mind as he demonstrates how a product idea is conceived, developed and then produced by a single craftsman with basic tools. Subjects covered are safety in the shop, use of tools, layout and pattern development, various ways of forming and joining metal along with edging methods, corner systems and panel reinforcement. You will be introduced to the basic sheet metal shop where you will learn about various methods of forming sheet metal and in some instances even constructing your own tools including a rather unique and functional 24" sheet metal brake constructed of hardwood. The final chapter opens with a mass production operation set up to demonstrate the efficiency and economy of modern industrial technology. Then further projects are progressively introduced as skill is acquired. Such projects as a dustpan for the shop, a handy tool tote tray as well as plans for single and double hinge tool boxes. By this time you are an advanced student and ready to construct the unique portable charcoal grill and the impressive three drawer tool chest from the plans provided. Dave Gingery brings it all within your grasp and you will be amazed at what can be produced with tin snips, standard measuring tools and a 24" sheet metal brake.

Computerized layout machines are so efficient that sheet metal pattern drafting is becoming a lost art. This book is designed for small shops that do not have layout machines or have a need for layout knowledge. This book is also valuable for those who want a fuller knowledge of the trade. --from the foreward.
