Available in PDF, EPUB and Kindle. Book excerpt: Applied Metal Forming: Including FEM Analysis describes metal forming theory and how experimental techniques can be used to study any metal forming operation with great accuracy. For each primary class of processes, such as forging, rolling, extrusion, wiredrawing, and sheet-metal forming, it explains how FEA (Finite Element Analysis) can be applied with great precision to characterize the forming condition and in this way optimize the processes. FEA has made it possible to build very realistic FEM-models of any metal forming process, including complex three-dimensional forming operations, in which complex products are shaped by complex dies. Thus, using FEA it is now possible to visualize any metal forming process and to study strain, stresses, and other forming conditions inside the parts being manufactured as they develop throughout the process.

This book was released on 1969 with total page 31 pages. Available in PDF, EPUB and Kindle. Book excerpt: The slab method of analysis for predicting forging stresses and loads has been applied to longitudinal (axial) flow, i.e., to extrusion-type forging. Both plane strain and axisymmetric deformations were considered. The flow models have been further studied, and the necessary equations for general use are derived. The flash-line location has been shown to have little effect upon maximum forging load if die-cooling effects are not too large. The present study represents a fundamental method for obtaining detailed information on the mechanics of closed-die forging.

Available in PDF, EPUB and Kindle. Book excerpt: Forging is one of the oldest metal working operations known and is used in making parts of widely varying sizes and shapes from variety of metals Closed die forging is one types of forging process in which different types metal are deformed plastically to obtain the required product geometry in a closed cavity that contains shape of the product. The physical phenomena of forging operations, which numerous advantages it has, therefore, are difficult to express with quantitative relationships. The metal flow, friction at the tool/material interface, the heat generation and transfer during plastic flow, and the relationships between microstructure/properties and process conditions are difficult to predict and analyze. Therefore, in most of the time products and their corresponding dies are made by trial and error to reach to the final correct product shape, which is a costly process as materials are wasted in the process as well as it takes considerable time of the expert involved in the operation. With the applications of finite elemental method some of the problems of analysis could be reduced significantly. FEM softwares are very much important in this regard.
Download or read book Metal Forming written by Taylan Altan and published by ASM International(OH). This book was released on 1983 with total page 384 pages. Available in PDF, EPUB and Kindle. Book excerpt: Briefly reviews the basic principles of metal forming but major emphasis is on the latest developments in the design of metal-forming operations and tooling. Discusses the position of metal forming in manufacturing and considers a metal-forming process as a system consisting of several interacting variables. Includes an overall review and classification of all metal-forming processes. The fundamentals of plastic deformation - metal flow, flow stress of metals and yield criteria - are discussed, as are significant practical variables of metal- forming processes such as friction, temperatures and forming machines and their characteristics. Examines approximate methods of analyzing simple forming operations, then looks at massive forming processes such as closed-die forging, hot extrusion, cold forging/ extrusion, rolling and drawing (discussion includes the prediction of stresses and load in each process and applications of computer-aided techniques). Recent developments in metal-forming technology, including CAD/CAM for die design and manufacture, are discussed, and a review of the latest trends in metal flow analysis and simulations.

This book was released on 2000 with total page 256 pages. Available in PDF, EPUB and Kindle. Book excerpt: The application of computer-aided engineering (CAE), design (CAD), and manufacturing (CAM), is essential in modern metal forming technology. Thus, process of modelling for the investigation and understanding of deformation mechanics has become a major concern in recent and advanced research, and the finite .element method (FEM.) has assumed increased importance, particularly in the modelling of deformation processes. This work is devoted to the development of CAD/CAM system for closed die forging process. The system development consists of three stages: namely, metal flow simulation, die failure analysis and design optimisation, and development and implementation of machining code. In the first stage, the finite element method was used to simulate the axisymmetric closed die forging process of copper material. The method was used to study the metal flow, die filling retaining the non-linearity involved in the large change in the geometry, the continuous change in the contact surface condition and the isotropic material work-hardening characteristics. In the second stage, a finite element analysis and optirnisation algorithm was developed to examine the die fatigue -life and to optimise the die design. The finite element analysis in the first and second stage was carried out using commercially available finite element software called LUSAS. In the third stage, a machining code for the optimised die was developed and implemented using CAD/CAM software called UniGraphics and CNC machine. A qualitative comparison between the computational results and experiments ware made. It had been found that the early stage of the metal flow in closed die forging was very similar to a simple upsetting, then the material flows into the die cavity and towards the flash land leading to a very sharp increase in forging load. The die was designed to sustain the forging load and withstand 1000 load cycles.

In addition, to lubrication effects, the effects of die chilling or heat transfer from a given lubricant, frication data obtained in hydraulic-press forging cannot be useful in mechanical press or hammer forging even if the die and the billet temperature are comparable.
