To obtain a high degree of flexibility and excellent surface finish in a manufacturing process, a lot of work is done on sheet metal by cutting it into a variety of shapes and sizes. The pneumatic Sheet Metal Clamping and Shearing Machine is one of the modern machines used to efficiently cut Sheet Metal to specification. This project on the Development of Sheet Metal Clamping and Shearing Machine discusses the maximum force that the cylinder actuator can exert on the workpiece, the shearing force required to cut sheet metals of 1.0mm, 1.2mm and 1.5mm for a length of 25mm. Also, a comparison of the time taken to cut sheet metals of 0.45mm, 0.6mm, and 0.8mm for a length of 50mm with a Manual Shearing Machine and Pneumatic Sheet Metal Clamping and Shearing Machine. The time by the Pneumatic Shearing Machine is less than that of the Manual Shearing Machine as shown in the presented table. Moreover, the cutting accuracy of the developed pneumatic Sheet Metal Clamping and Shearing Machine was compared with the Manual Metal Shearing Machine, and observations made, showed that the Pneumatic Clamping and Shearing Machine has greater accuracy than the Manual Shearing Machine as a result of the clamping device on the machine which gives it greater clamping rigidity on the workpiece for the cutting operation to be carried out. The project had been able to address the following: Production time reduction, increase in cutting accuracy, and elimination of manually applied effort.
