This project work deals with the design of pneumatically controlled small scale punching machine to carry out piercing operation on thin sheets (1-2 mm) of different material like aluminum and plastic having tensile strength of 180N/mm2 and 90 N/mm2.The compressed air from the compressor at the pressure of 8 to 12 bar is passed through a pipe connected to the solenoid valve, so the press force(cutting force +stripping force) is 10350N.Reduction in punching force requirement being the main aim of this project work is obtained by modification in punch tool design i.e. by provision of shear on punch face. Subsequently it results in reduction in amount of punching force requirement. And further a SOLIDWORKS model of the machine is developed on the basis of calculations with respect to punching force requirement
