Abstract

Over the past century, manufacturing has made considerable progress new machine tools, highperformance cutting tools and modern manufacturing processes enable today’s industries to make parts faster and better than ever before. Although work holding methods have also advanced considerably, the basic principles of clamping and locating are still the same. In traditional machining fields or modern flexible manufacturing systems, the work piece holding is the first issue of the machining operation to be confronted. Fixtures are the special production tools which make the standard machine tool, more versatile to work as specialized machine tools. Fixture design is a critical manufacturing activity in the production cycle and has great effect on product quality, lead time, and cost targets, and labour skill requirements in product manufacturing. This paper gives detailed description on designing a Milling fixture so that milling operation is performed properly to obtain required dimension for an aluminum component used in an aerospace application. It also includes the detailed result of analysis done for the assembled fixture, to know the behavior of the component against the operating load.The proposed fixture is designed to adopt cost effective manufacturing process so that it can be machined easily with a lesser time and in turn it saves the machining time and manufacturing cost.
