چکیده
Electromagnetic forming (EM forming or magneforming) is a type of high velocity, cold forming process for electrically conductive metals, most commonly copper and aluminum. The work piece is reshaped by high intensity pulsed magnetic fields that induce a current in the work piece and a corresponding repulsive magnetic field, rapidly repelling portions of the work piece. The work piece can be reshaped without any contact from a tool, although in some instances the piece may be pressed against a die or former. The technique is sometimes called high velocity forming.

Cloud manufacturing is defined as a relationship between the consumer and a flexible array of production services, managed by an intervening architecture that can match service providers to product and manufacturing processes Cloud manufacturing definitions typically make explicit or imply three groups of actors: consumers, who request and use cloud manufacturing processes; application provider...
متن کاملModern Manufacturing Processes: A Review
Necessity to use new materials, demanding functional requirements and miniaturization have led to evolution of modern manufacturing processes. Developments are taking place both in the conventional methods and unconventional methods of manufacture. High speed machining, hard machining, non conventional processes like beam, mechanical and chemical processes and additive processes like rapid prot...
متن کاملCapability Indices for Rayleigh Process
Monitoring, control and improvement of quality are important for companies. Process capability indices (PCIs) are tools widely used by the industries to determine the quality of their products and the performance of their manufacturing processes. Classic versions of these indices were constructed for processes whose quality characteristics have a normal distribution. But, many of these ...
متن کاملMICROSTRUCTURE, HARDNESS AND SURFACE ROUGHNESS CHARACTERIZATION OF EBM FABRICATED Ti-6Al-4V SAMPLES
Electron beam melting (EBM) is among the modern additive manufacturing processes whereby metal powders are selectively melted to produce very complicated components with superior mechanical properties. In this study, microstructure, hardness, and surface roughness of EBM fabricated Ti6Al4V samples were characterized. The results showed that the microstructure consisted of epitaxially-grown prim...
متن کاملTheoretical, numerical, and experimental analyses of free vibrations of glass fiber reinforced polymer plates with central cutouts and free boundaries
This study explored the free vibration problem in relation to glass fiber reinforced polymer (GFRP) plates with central cutouts and free boundaries using theoretical, experimental, and numerical methods. The theoretical formulations were derived from the classical lamination plate theory. The rectangular cutout was mathematically modeled into the stiffness matrix of the plate by multiplying Hea...
