From P. N. Rao, Manufacturing Technology, Tata McGraw Hill, 1998. Stretch forming, hydro forming, spinning are some of such processes. These operations are usually carried out with automated machinery at manufacturing plants. le filetage). Transfer dies : Sheet metal undergoes different operations at different stations in a straight line or circular path. The complex shape products with high strength and rigidity and small mass are produced in the process of separating, shaping and assembly operations; they are widely 0000001784 00000 n For this reason, lubrication is vital for successful sheet metal forming. Sheet metal working may be defined as a chip-less manufacturing process by which various components are made from sheet metal. Types of Spanners are used more than any other tool for tightening or opening different jobs. Piercing is the process in which desired shape holes are produced in a piece of sheet metal without eliminating any material from the sheet or removing a very small amount of material as shown in the figure. Saif M. is a Mechanical Engineer by profession. It is used in 1. The set up is similar to that used in blanking welding operations, the weldabilty of the materials in use is very important. In this post, you'll learn what is Jig Boring Machine. Material elements experience different amounts, and proportions, of bi-axle stress and strain depending upon their location within the work. Duncan The University of Auckland, New Zealand S.J. The length of the object to be drawn is less than its width. For example, a flat sheet of aluminum is less stiff than that same sheet of aluminum bent into a V cross section. Typical tools used for drawing are shown.
