This book was released on 1984 with total page 11 pages. Available in PDF, EPUB and Kindle. Book excerpt: Theoretical studies for the pressure-assisted deep-drawing operation have been conducted to determine the largest cup that could be drawn for different materials. Theoretical results for materials characterized by material constant n values and normal anisotropy R values were obtained considering the coefficient of friction ? as 0.0, 0.05, 0.1, and 0.2 values. Tensile instability is shown to be the most appropriate condition in controlling the limiting drawing ratio for the pressure process. Smooth and rough, hemispherical and conical headed punches were used to obtain practical limiting drawing ratios using different materials and different lubricants. Sheet metals used in this work were annealed 70/30 brass, mild steel, and annealed aluminum. Sheet metals were characterized by the relation effective stress ? = A?n where A is a material constant and ? is strain. The anisotropy of the sheet metal was measured by R value for the rolling direction, 45° to the rolling direction and perpendicular to the rolling direction. A test rig, with a specially designed relief valve that controlled pressure in a range from zero up to 100 MPa and a specially designed strain gauge load cell, were constructed to carry out the experimental work. The pressure-assisted deep-drawing has been experimentally proven to be successful in obtaining higher limiting drawing ratios when deep-drawing with hemispherical and conical headed punches. Comparison between theoretical results and experimental results and the experiments of previous research workers has demonstrated the importance of taking friction into account in the theoretical analysis.

Available in PDF, EPUB and Kindle. Book excerpt: This book helps the engineer understand the principles of metal forming and analyze forming problems - both the mechanics of forming processes and how the properties of metals interact with the processes. In this fourth edition, an entire chapter has been devoted to forming limit diagrams and various aspects of stamping and another on other sheet forming operations. Sheet testing is covered in a separate chapter. Coverage of sheet metal properties has been expanded. Interesting end-of-chapter notes have been added throughout, as well as references. More than 200 end-of-chapter problems are also included.
Download or read book Modern Manufacturing Processes written by Muammer Koç and published by John Wiley & Sons. This book was released on 2019-09-04 with total page 549 pages. Available in PDF, EPUB and Kindle. Book excerpt: Provides an in-depth understanding of the fundamentals of a wide range of state-of-the-art materials manufacturing processes Modern manufacturing is at the core of industrial production from base materials to semi-finished goods and final products. Over the last decade, a variety of innovative methods have been developed that allow for manufacturing processes that are more versatile, less energy-consuming, and more environmentally friendly. This book provides readers with everything they need to know about the many manufacturing processes of today. Presented in three parts, Modern Manufacturing Processes starts by covering advanced manufacturing forming processes such as sheet forming, powder forming, and injection molding. The second part deals with thermal and energy-assisted manufacturing processes, including warm and hot hydrostamping. It also covers high speed forming (electromagnetic, electrohydraulic, and explosive forming). The third part reviews advanced material removal process like advanced grinding, electro-discharge machining, micro milling, and laser machining. It also looks at high speed and hard machining and examines advances in material modeling for manufacturing analysis and simulation. Offers a comprehensive overview of advanced materials manufacturing processes Provides practice-oriented information to help readers find the right manufacturing methods for the intended applications Highly relevant for material scientists and engineers in industry Modern Manufacturing Processes is an ideal book for practitioners and researchers in materials and mechanical engineering.
Download or read book Correlation of Deep drawing Press Performance with Tensile Properties written by American Society for Testing and Materials and published by . This book was released on 1965 with total page 38 pages. Available in PDF, EPUB and Kindle. Book excerpt: Interlaboratory tests were conducted on 0.036-in.-thick sheet specimens of aluminum-killed steel to determine whether correlation between pressing quality and plastic strain ratio r, strain-hardening exponent n, and other tensile properties could be established. Metallurgical treatments of the specimens were varied to obtain four combinations or r and n: High r and high n, high r and low n, low r and high n, and low r and low n. The Nelson-Winlock method was used for measurement of n, and the procedure suggested by the International Deep Drawing Research Group was used for measurement of r. Good interlaboratory correlation was shown for values of r, but values of n, though adequate, did not correlate nearly as well. The specimens were subjected to three stamping operations in the production of: a panel truck door, a blower housing, and an automotive instrument panel. Press quality was evaluated by the percentage of breakage occurring during a lift. The test results demonstrate the differences in dependence on r and n of parts involving different degrees of drawing and stretching. The door panel, primarily a punch stretching operation, correlated best with r and showed little dependence on n. The blower housing correlated best with r, and the instrument panel showed a strong dependence on both r and n.
