Experimental and Computational Analysis of Various Design Parameters of Automotive Component Using Rapid Prototyping

Abstract

Manufacturing is one of the most vital wheel cogs for the developing country like India. newlineGovernment of India is planning to increase the manufacturing capacity of the country newlineand place the India as a manufacturing hub in the world map. India is planning to newlineincrease share of the manufacturing industry of the gross domestic product GDP. newlinePrototyping is an important step for the conceptualization of any design and mould newlinemaking process. Nowadays, several prototyping processes are available. Among all the newlineavailable prototyping processes, rapid prototyping process takes minimum time to make newlinethe prototype model from the 3D CAD model. However, the quality of prototype model newlineproduced through rapid prototyping process is inferior over the traditional methods of newlineprototyping. Several reports and published articles are available in the international and newlinenational journal and which show that the quality of prototype model produced through newlinethe rapid prototyping process is depends upon the printing process parameters. newlineThe main focus of this research is to propose the methodology to improve the newlinequality of prototype model developed through the commonly used rapid prototyping newlinetechnology namely FDM and PolyJet. In this thesis, initially a comparison is being newlinemade for FDM and PolyJet technology. Comparative study are carried out on the basis newlineof flatness, cylindricity, roundness, percentage errors in the linear dimension, newlinepercentage error in the radial dimension, surface roughness and cost of the prototype newlinemodel developed via FDM and PolyJet process. For the comparative study of FDM and newlinePolyJet technology, a complex shaped product, radial engine connecting rod was newlineconsidered. The selected automotive component has cylindrical, linear, radial dimensions newlineand flat surface.
