The sheet metal cutting process has a vital role in all kind of industries. Generally in medium and small scale industries this machine is manually hand operated. In our project is SHEET METAL CUTTING MACHINE BY USING SOLENOID VALVE . Automation in the modern world is inevitable. Any automatic machine is designed for the economical use of man, machine, and material worth the most. In our project solenoid valve is key for the automation. The working principle of pneumatic double acting cylinder is mainly involved in the sheet metal cutting machine. The piston is associated to the moving cutting tool and thus sheet metal is cut into the small sizes. As the machine is portable in size it s easy to transport.
