The pneumatic system has gained a large amount of importance in last few decades. This project work mainly includes the main components of designs of pneumatic operated washer making machine such as: design of cylinder, selection of direction control valve, and selection of tube, design of aluminum sheet, plastic sheet, tar felt sheet and pneumatic circuit design. Design analysis also done by using CATIA software. Fabrication and implementation includes: fabrication of frame and components. This importance is due to its accuracy and cost. Due to ease of operation, handiness, and expediency in operating the pneumatic system has made us to design and fabricate this unit as our project. This pneumatic operated washer making machine unit, as we hope that it can be operated easily with partially skilled operators also. The pneumatic operated washer making machine has an advantage of working in low shear strength pressure, that is even a shear strength of 72 N/mm 2 is enough for operating the unit. Different types of pneumatic operated washer making machines as requirement can be thus got. According to the work material the operating shear strength can be varied.

In this project, authors used punching process and bending process for simple application and using the foot operated valve instead of hand operated lever so single man can perform the operation of machine like punching easily. In today’s practical and cost-conscious world, sheet-metal parts have already replaced many expensive cast, forged, and machined products. The reason is obviously the relative economy of operation, easier implementation for mass-production, as well as greater control on the technical parameters. In almost all of the sheet metal operations punching or pressing operation is the major or primary operation in the process operation series. Automation, this operation results in reduced lead time and also can decrease human attempt. Automation can be defined as the “technology related with application of electrical, mechanical, electronic and computer-based integrated systems to operate and control production process”. There are many reasons for automating the process. The reason may be to reduce manufacturing lead time, to increase labour productivity or to improve the worker safety, etc. Sheet metals are frequently employed for industrial and end user parts because of its high capacity for being bent and formed into complex shapes. Galvanized iron, tin plates, copper, brass, zinc, aluminium etc. metals are regularly utilized. Sheet metal parts include automotive industry, agricultural machinery parts, and aerospace applications as well as consumer equipments. Choice of sheet metal forming operation depends on the selection of
