Publish Date: 2006-01-01
Features: This book is divided into seven chapters. Chapters 1 and 2 introduce the fundamental knowledge of sheet metal unfolding and layout technology, providing a comprehensive overview of plane geometry drawing methods and orthogonal projection knowledge, the projection characteristics of points, lines, surfaces, and solids, as well as methods for determining the true length of line segments and the intersection lines of surfaces. Chapters 3 to 6 discuss layout methods in detail, elaborating on three basic methods for creating development drawings—parallel line method, radial line method, and triangle method. With a comprehensive understanding of sheet metal unfolding technology, readers can master the steps and methods of layout by applying typical construction drawings to different component shapes. Chapter 7 focuses on the cutting methods for steel structural members, primarily introducing the calculation of material lengths for various bent shapes of steel sections and the specific methods for cutting openings. This book is suitable for sheet metal workers and riveters in machinery and equipment manufacturing plants, metal structure factories, and the construction industry. It can also serve as a reference for teachers and students in technical schools and vocational and technical schools.
