Book Description
Quality and preciseness requirements for automobile parts are getting more severe year by year. One of the significant factors to determine a high quality automobile is their appearance. The outer panel surface quality includes the matching quality among press- formed parts and fitting quality which involves the dimensions of uniformity in clearance and level-mismatch between panels. A number of automotive interior and exterior panels are formed by press brake bending or flanging, then joined by hemming. Therefore, the way to get higher quality appearance is to improve press brake technologies. Traditionally the design process for bending, flanging and hemming tools are based on trial-and-error processes and on the skill of experienced die-makers. This approach results in high development cost and long lead-times. Computer simulations are good tools to predict and evaluate the tool and process design. The improvement of computer hardware and software has permitted "virtual" metal forming processes to be conducted on digital computers. Finite element method (FEM) is a numerical procedure for analyzing problems that are too complex to be solved by classical analysis methods. The main objectives of this study are to investigate the flat surface-straight edge, flat surface-contour edge and curved surface-straight edge flanging and hemming processes. Furthermore, The development of new tool design method for flanging and hemming is included. To achieve these goals, numerical models and finite element analysis were performed to compare with experimental data. Besides, industrial flanging and hemming case studies were conducted by commercial FEM package. Consequently, a set of part, process and die design rules and guidelines for bending, flanging and hemming were developed.

Book Description
Descripción del editor: "heet forming fundamentals are thoroughly addressed in this comprehensive reference for the practical and efficient use of sheet forming technologies. The principle variables of sheet forming-including the interactions between variables-are clearly explained, as a basic foundation for the most effective use of computer aided modeling in process and die design.Topics include stress analysis, formability criteria, tooling, and materials for sheet forming. The book also covers the latest developments in sheet metal forming technology, including servo-drive presses and their applications, and advanced cushion systems in mechanical and hydraulic presses."

Book Description
Following the long tradition of the Schuler Company, the Metal For ming Handbook presents the scientific fundamentals of metal forming technology in a way which is both compact and easily understood. Thus, this book makes the theory and practice of this field accessible to teaching and practical implementation. The first Schuler "Metal Forming Handbook" was published in 1930. The last edition of 1966, already revised four times, was translated into a number of languages, and met with resounding approval around the globe. Over the last 30 years, the field of forming technology has been rad ically changed by a number of innovations. New forming techniques and extended product design possibilities have been developed and introduced. This Metal Forming Handbook has been fundamentally revised to take account of these technological changes. It is both a text book and a reference work whose initial chapters are concerned to pro vide a survey of the fundamental processes of forming technology and press design. The book then goes on to provide an in-depth study of the major fields of sheet metal forming, cutting, hydroforming and solid forming. A large number of relevant calculations offers state of the art solutions in the field of metal forming technology. In presenting tech nical explanations, particular emphasis was placed on easily under standable graphic visualization. All illustrations and diagrams were compiled using a standardized system of functionally oriented color codes with a view to aiding the reader's understanding.

Book Description
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 illsutrates several dfifferent approaches to theis intricate field by taking the reader through the 'hos' and 'whys' of product analysis, as well as the technqiues for blanking, punching, bending, deep drawing, stretching, material economy, strip design, movement of metal duting stamping, and tooling.
