Joshi Press Tool Design By PH Joshi Introduction of Sheet Metal Working Process How to produced Sheet? Press working has been defined as a chipless manufacturing process by which components are made from sheet metal. The Press machine working operations are carried out with the help of a metal forming machine called press which shear or forms the component by applying force. The main features of the press include a frame that supports a ram or a slide, a bed and a source of power with a mechanism for operating the ram inline or at right angles to the bed. The ram is equipped with a punch or a set of punches that have the shape of the job to be produced while a die block is attached to the bed. Workpieces are produced or formed as the pun...

Computational Fluid Dynamics (CFD)

Computational Fluid Dynamics Introduction A Brief History of CFD Since the dawn of civilization, mankind has always had a fascination with fluids; whether it is the flow of water in rivers, the wind and weather in our atmosphere, the smelting of metals, powerful ocean currents, or the flow of blood around our bodies. Heraclitus 536 - 470BC Archimedes 287 - 212BC In antiquity, great Greek thinkers like Heraclitus postulated that "Everything flows" but he was thinking of this in a philosophical sense rather than in a recognizably scientific way. However, Archimedes initiated the fields of static mechanics, hydrostatics, and determined how to measure densities and volumes of objects. The focus at the time was on waterworks: aqueducts, canals, harbors, and bathhouses, which the ancient Romans perfected to a science. It was not until the Renaissance that these ideas resurfaced again in Southern Europe when we find great artists cum engineers like Leona...
