Computer Applications in Near Net-Shape Operations


Book Description

The process of producing components to final net-shapes is fast becoming a desirable goal for metal working industries. This is due to a combination of factors such as the development of new materials and escalating energy costs. This book addresses the design, analysis and simulation of near net-shape operations using some of the most advanced computer techniques and tools available. Topics covered include: sheet metal forming operations: progressive stamping, fine blanking, nesting, flat pattering, bending and nibbling; die design, construction and NC programming of wire EDM; bulk metal forming processes such as cold upsetting and close-die forging; injection mould design, analysis and simulation; computer-aided design of CNC machines for near net-shape operations; and intelligent progressive die design system IPD. This collection of the latest developments from experts in the field should be of interest to practising engineers, graduate students and researchers of metal forming, stamping, mould and die design.




Computer Applications in Near Net-Shape Operations


Book Description

Having edited "Journal of Materials Processing Technology" (previously entitled "Journal of Mechanical Working Technology") for close on 25 years, I have seen the many dramatic changes that have occurred in the materials processing field. Long gone are the days when the only "materials processing" carried out was virtually the forming of conventional metals and alloys, and when the development of a new product or process in a great number of cases called for several months of repetitive trial-and-error,' with many (mostly intuition- or experience-based) expensive and time-consuming modifications being made to the dies, until success was achieved. Even when a 'successful' product was formed, its mechanical properties, in terms of springback and dimensional accuracy, thickness variations, residual stresses, surface finish, etc. , remained to be determined. Bulk-forming operations usually required expensive machining to be carried out on the product to impart the required dimensional accuracy and surface fmish. Over the years, the experience-based craft of metal forming has given way to the science of materials processing. With the use of the computer, forming operations can be simulated with accuracy, to determine the best forming route and the associated forming loads and die stresses, and to predict the mechanical properties of the formed product, even down to its surface texture.




Hierarchical Operations and Supply Chain Planning


Book Description

This title describes the application of hierarchical planning techniques to all the major functional areas of supply chain planning, including production, distribution, warehousing, transportation, inventory management, forecasting and performance management. In particular, the book provides a comprehensive review and understanding of how hierarchical planning techniques and principles can contribute to the effective and efficient management and planning of supply chain activities. The book begins with a review of some well-known, original hierarchical production planning techniques and implementations dating back several decades. Building on this historical base, it then reviews numerous more current hierarchical planning methods and applications covering a wide array of supply chain activities. Additionally, the book offers a number of new and original hierarchical planning techniques and algorithms covering different components of supply chain planning.




Computer Aided and Integrated Manufacturing Systems


Book Description

This is an invaluable five-volume reference on the very broad and highly significant subject of computer aided and integrated manufacturing systems. It is a set of distinctly titled and well-harmonized volumes by leading experts on the international scene. The techniques and technologies used in computer aided and integrated manufacturing systems have produced, and will no doubt continue to produce, major annual improvements in productivity, which is defined as the goods and services produced from each hour of work. This publication deals particularly with more effective utilization of labor and capital, especially information technology systems. Together the five volumes treat comprehensively the major techniques and technologies that are involved. Contents: .: Techniques and Applications of Production Planning in Electronics Manufacturing Systems (J Smed et al.); Economic Optimization of Machining Operations in Computer Aided Manufacturing Systems (J Wang); Computer Techniques and Applications for Real-Time Embedded Control in Mechatronic Systems (M Colnaric & W A Halang); and other articles. Readership: Graduate students, academics, researchers, and industrialists in computer engineering, industrial engineering, mechanical engineering, systems engineering, artificial intelligence and operations management
