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. Keywords-Design and modeling of components, Designing components of the pneumatic system, Fabrication of pneumatic sheet metal clamp making the machine

Automation within the contemporary world is inevitable. Any automatic machine focuses towards the economical use of man, machine and material well worth the most. For small and tiny scale industrial units the sheet cutting machine is manually operated. In this paper, solenoid valve and Arduino controller is used for automation. The machine works with the help of double acting pneumatic cylinder. The piston is connected to the moving cutter. The machine is easy to transport and transfer. The compressed air from the compressor is used as the force medium for this operation. There are double acting pneumatic cylinders, solenoid valves, flow control valves and the Arduino is used. The arm from the compressor enters to the solenoid valve. The function of solenoid valves all of air correct time interval. The 5/2 solenoid valve is used. At one position the piston is pushed by the air entering the cylinder thus obtaining cutting stroke. The releasing stroke is obtained by the movement of piston in backward direction due to the air entering the cylinder from the other side. The speed of the cutting and releasing stroke is varied by the Arduino controller.
