This book was released on 2012-12-06 with total page 468 pages. Available in PDF, EPUB and Kindle. Book excerpt: The importance of proper geometric dimensioning and tolerancing as a means of expressing the designer's functional intent and controlling the inevitable geometric and dimensional variations of mechanical parts and assemblies, is becoming well recognized. The research efforts and innovations in the field of tolerancing design, the development of supporting tools, techniques and algorithms, and the significant advances in computing software and hardware all have contributed to its recognition as a viable area of serious scholarly contributions. The field of tolerancing design is successfully making the transition to maturity where deeper insights and sound theories are being developed to offer explanations, and reliable implementations are introduced to provide solutions. Machine designers realized very early that manufacturing processes do not produce the nominal dimensions of designed parts. The notion of associating a lower and an upper limit, referred to as tolerances, with each dimen sion was introduced. Tolerances were specified to ensure the proper function of mating features. Fits of mating features included clearances, location fits, and interference fits, with various sub-grades in each category assigned a tolerance value depending on the nominal size of the mating features. During the inspection process, a part is rejected if a dimension fell outside the specified range. As the accuracy requirements in assemblies became tighter, designers had to consider other critical dimensions and allocate tolerances to them in order to ensure the assembly's functionality.
Download or read book Unit Manufacturing Processes written by National Research Council and published by National Academies Press. This book was released on 1995-02-03 with total page 229 pages. Available in PDF, EPUB and Kindle. Book excerpt: Manufacturing, reduced to its simplest form, involves the sequencing of product forms through a number of different processes. Each individual step, known as an unit manufacturing process, can be viewed as the fundamental building block of a nation's manufacturing capability. A committee of the National Research Council has prepared a report to help define national priorities for research in unit processes. It contains an organizing framework for unit process families, criteria for determining the criticality of a process or manufacturing technology, examples of research opportunities, and a prioritized list of enabling technologies that can lead to the manufacture of products of superior quality at competitive costs. The study was performed under the sponsorship of the National Science Foundation and the Defense Department's Manufacturing Technology Program.
Download or read book Computer Methods for Tolerance Design written by Robert G. Wilhelm and published by World Scientific. This book was released on 1992 with total page 170 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book describes recent research advances and computer tools that can be applied in the determination of geometric tolerances. A framework for tolerance synthesis is developed and used with artificial intelligence techniques to provide computer methods for both analysis and synthesis of geometric tolerance specifications. Tolerance primitives, based on a sound theory of tolerancing, are used to represent tolerance relationships or links between geometric entities and functional requirements. Algorithms are developed for the determination of boundedness and the measurement of sufficiency. A detailed constraint network is used to represent tolerance relations for a part under design and provide for the composition of tolerance specifications.

Available in PDF, EPUB and Kindle. Book excerpt: Effective design and manufacturing, both of which are necessary to produce high-quality products, are closely related. However, effective design is a prerequisite for effective manufacturing. This new book explores the status of engineering design practice, education, and research in the United States and recommends ways to improve design to increase U.S. industry's competitiveness in world markets.

Download or read book Concurrent Design of Products Manufacturing Processes and Systems written by Ben Wang and published by CRC Press. This book was released on 1999-01-27 with total page 390 pages. Available in PDF, EPUB and Kindle. Book excerpt: Methods presented involve the use of simulation and modeling tools and virtual workstations in conjunction with a design environment. This allows a diverse group of researchers, manufacturers, and suppliers to work within a comprehensive network of shared knowledge. The design environment consists of engineering workstations and servers and a suite of simulation, quantitative, computational, analytical, qualitative and experimental tools. Such a design environment will allow the effective and efficient integration of complete product design, manufacturing process design, and customer satisfaction predictions. This volume enables the reader to create an integrated concurrent engineering design and analysis infrastructure through the use of virtual workstations and servers; provide remote, instant sharing of engineering data and resources for the development of a product, system, mechanism, part, business and/or process, and develop applications fully compatible with international CAD/CAM/CAE standards for product representation and modeling.

This book was released on 2001-08-31 with total page 148 pages. Available in PDF, EPUB and Kindle. Book excerpt: When the Cold War abruptly ended, DOE halted most nuclear materials production. In 1995, Congress chartered DOE's Environmental Management Science Program (EMSP) to bring the nation's scientific infrastructure to bear on EM's most difficult, long-term cleanup challenges. The EMSP provides grants to investigators in industry, national laboratories, and universities to undertake research that may help address these cleanup challenges. On several occasions the EMSP has asked the National Academies for advice on developing its research agenda. This report resulted from a 15-month study by an Academies committee on long-term research needs for deactivation and decommissioning (D&D) at DOE sites.
