Abstract : Abstract— Automobile Industry in the world has grown exponentially in the recent decades. Various business models are adopted for the growth of the Industry. Among this Six Sigma is a problem solving approach which focuses on the variation reduction in any manufacturing or service industry. Six Sigma uses structured problem solving approach as DMAIC ( Define, Measure, Analyse, Improve and Control ). The project work is carried out in Load Conscious Regulating Valve assembly which is used in Automobile braking system to avoid rear wheel locking. In this project LCRV valve assembly line is chosen based on Pareto Analysis. Various Six Sigma tools such as Repeatability and Reproducibility Study, Component Search Method are used to identify the root cause for the problem. Based on the root cause analysis improvement actions are taken to reduce the defect. In this project the material of the pressing tool plays a significant role. Various tool materials are chosen and trials conducted for better performance. Latest coatings like Physical Vapor Deposition and Chemical Vapor deposition are explored. PVD coating using TiAlN is coated as the countermeasure. The results are validated through statistical methods. Through Six Sigma techniques the defect in the LCRV assembly line is reduced.
