A pneumatic machine is for sheet metal industry and can be made into multiple machines and should be used as “U” shaped clamp and also circle cutting cum straight cutting machine. This machine is simple to maintain easy to operate. Hence we tried out hands-on Pneumatic Shearing Machine In shearing operation as the punch descends upon the metal, the pressure exerted by the punch first cause the plastic deformation of the metal. Since the clearance between the punch and the die is very small, the plastic deformation takes place in a localized area and the metal adjacent to the cutting edges of the punch and die edges becomes highly stressed, which causes the fracture to start on both sides of the sheet as the deformation progresses. And the working of the pneumatic system depends upon air compressor, which converts mechanical energy into, pressure energy of compressed air. The compressed air should be proposed to move the piston of the pneumatic cylinder. The linear movement of the piston and piston rod can be used to get various mechanical operations like bending, cutting, punching, and hammering etc.
