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 punch descends onto the die block.
  • In most cases processing of sheet metal is done in the cold state. Material like magnesium may sometimes be heated slightly to make them more workable.
  • Press tool operation of sheet metal is by far the cheapest and fastest method to complete the manufacturing of component
History of Press Machine: The Press Machine of Historically, metal was shaped by hand using a hammer. Later, larger hammers were constructed to press more metal at once or to press thicker materials. Often a smith would employ a helper or apprentice to swing the sledgehammer while the Smith concentrated on positioning the workpiece. Adding windmill or steam power yielded still larger hammers such as steam hammers. Most modern machine presses use a combination of electric motors and hydraulics to achieve the necessary pressure. Along with the evolution of presses came the evolution of the dies used within them.

PRESS TOOL: A machine press, commonly shortened to press, is a machine tool that changes the shape of a workpiece. Press tools are commonly used in hydraulic and mechanical presses to produce components at a high productivity rate. Generally, press tools are categorized by the types of operation performed using the tool, such as blanking, piercing, bending, forming, forging, trimming, etc. The press tool will also be specified as a blanking tool, piercing tool, bending tool, etc.

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...
