IRJET -Fabrication of Pneumatic Sheet Metal Shearing Machine

The document describes the fabrication of a pneumatic sheet metal shearing machine. It uses a pneumatic cylinder powered by compressed air to cut sheet metal. The pneumatic cylinder is connected to a moving cutting blade. Depressing a directional control valve admits compressed air to either end of the cylinder, driving the blade up or down to cut the sheet metal. This automatic machine is intended to improve productivity over manual sheet metal cutting. It allows repetitive cuts with consistent dimensions to be made more quickly and easily than by hand. The pneumatic design makes it cheaper than a hydraulic alternative while being suitable for small scale metal cutting applications.
