A fixture is the most effective tool used to maintain the tolerance and precision in manufacturing industries. This project revolves around the development of fixture to manufacture the chassis of asphalt paver vehicle from L&T construction equipment ltd. The design of the fixture is optimized to provide the company to build the chassis more effective and precise with the knowledge acquired during the literature survey. The fixture is set up on the dowel-pin platform. The project will give an overall development of a fixture from the design process till the scaled prototype going under multiple iterations of analysis through Finite Element Analysis Method. The parameter or the constraints in the design are studied thoroughly such that no failure of the fixture occurs during high volume manufacturing in the company. The end product will be designed considering parameter which could be affected by various shop floor activities. Also carried out tolerance stack-up analysis to find out whether the introduced precision tolerance at the component level is meeting the assembly level functional requirement. The material selected for fabricating the fixture is specified for frequent periodic usage and open environment. The final product will meet all the requirements for large volume manufacturing in L&T construction equipment ltd.
