Abstract

Fixtures play an important role within many manufacturing processes. They accurately locate and secure a work piece during machining such that the part can be manufactured to design specifications. Thus fixtures have a direct effect upon machining quality, productivity, and the cost of products. Fixture is a special purpose tool which is used to facilitate production (machining, assembling and inspection operations) when work pieces are to be produced on a mass scale. This project consists of a flange named as Flange yoke used in TATA 407 vehicle (a part of propeller shaft) which is manufacturing in MSL Driveline System Limited. The current system carries out the drilling process on the forged part of the flange. This causes misalignment of drill up to 0.2-1 mm .Hence it results into increase in rejections. To overcome this problem a new fixture is to be designed, which will hold the flange from its bottom side where the machined surface is available for drilling. This will reduce the chance of misalignment of drill and will maintain the concentricity with the locating diameter. This will maintain the quality of the product.
