Significance of Sheet Metal Fabrication
Sheet Metal Fabrication refers to the bending and shaping processes of sheet metal techniques. Sheet metals can be given all sorts of complex hollow shapes and sections, and the equipment used for these processes, range from simple hand tools, to sophisticated power-operated automatic machinery . Sheet metal work usually starts with a preliminary operation such as cutting, perforating or slitting etc. with tools that exercise some type of shearing action. These may be simple hand scissor like cutting tools , or power operated bench shears for heavier gauge materials . There are several kinds of power-driven shearing machines, and such machines comprises of a fixed blade and a movable blade . The process of 'punching' refers to operations carried out with the use of a punching machine (or press) and this means to pierce a hole in the metal article , with the appropriate tool fitted in the machine, and clipping (the removal of surplus metal). Another type of sheet metal fabr...
