Design and Fabrication of Turning Fixture and Drilling Jig for Exhaust Manifold

Abstract

The successful running of any mass production depends upon the interchangeability to facilitate easy assembly and reduction of unit cost. Mass production methods demand a fast and easy method of positioning work for accurate operations on it. Jigs and fixtures are production tools used to accurately manufacture duplicate and interchangeable parts. Jigs and fixtures are specially designed so that large numbers of components can be machined or assembled identically, and to ensure interchangeability of components. To eliminate marking, punching, positioning, alignments etc. It will make easy, quick and consistently accurate locating, supporting and clamping the blank in alignment of the cutting tool. Guidance to the cutting tool like drill, reamer etc. Increase in productivity and maintain product quality consistently. It will reduce operator's labour and skill -requirement, Also reduce measurement and its cost .Enhancing technological capacity of the machine tools. Reduction of overall machining cost and also increases in interchangeability.
