Forging, one of many manufacturing process, is where metal is pressed, pounded or squeezed under great pressure into high strength parts known as forgings. The process begins with starting stock which is heated to its plastic deformation temperature, then upset between dies to the desired shape and size. It is important to note that the forging process is entirely different from the casting (or foundry) process, as metal used to make forged parts is never melted and poured (as in the casting process). During this hot forging process, coarse grain structure is broken up and replaced by finer grains. Mechanical properties are therefore improved through reduction of cast structure, voids and segregation. Forging also provides means for aligning …show more content…

In this essay, the author

  • Explains the process of forging, whereby metal is pressed, pounded, or squeezed under great pressure into high strength parts.
  • Explains that open-die forging uses a hammer to repeatedly strike the workpiece to deform it.
  • Explains that human muscle power can be a good alternative to meet the energy requirements for performing many economic activities like hammering.
  • Explains how the pedal-driven hammer uses human energy and stores it in a flywheel at an energy-input rate convenient to the peddler.
  • Explains that the pedal hammer is designed for precision work with comfort and safety. a miss-strike could kick a chasing tool out of the treadle and injure the tool-holding hand.
  • Explains that the pedal-driven hammer can be disassembled into upper and lower parts for space-conserving positioning. its safety design, speed of operation, portability in and out of the studio, low cost, and comfortable ergonomics make it useful for wood and leather working.

After ancient people used and later mastered both fire and metals, they attempted to heat basic metallic compounds and pound them into primitive tools they would use when they went to wars, go out hunting animals to feed themselves and later farming. The art of forging, shaping metal using heat and pressure, progressed until the Dark Ages which was the same time that most industrial, scientific and cultural advancements stopped. Possession of metals was highly regarded as a sign of wealth before then.
Primarily, forging is an art but it was incorporated with some unique methods by blacksmiths so they would ensure repeatability of the practice, quality of finish parts and efficiency in their workshop operations in past centuries. Advancements in chemistry helped realize improved means of production and the discovery of stronger materials. Preliminary recipes for forging metallic compounds helped yield great scientific expertise during the Industrial …show more content…

It is a major world-wide industry that has had significant contributions to the development of man. The forging process can create parts that are stronger than those manufactured by any other metalworking process. This is why forgings are almost always used where reliability and human safety are critical. But you'll rarely see forgings, as they are normally component parts contained inside assembled items such as airplanes, automobiles, tractors, ships, oil & gas drilling equipment, engines, missiles and all kinds of capital
