This paper presents a Lean Six Sigma improvement in a production line of the company’s Carbon Bush Machining Sector, in order to eliminate losses that cause low productivity, affecting the fulfillment of the production plan and customer satisfaction. The use of Lean methodology following the DMAIC (Define, Measure, Analyze, Improve and Control) stages allowed analysing the factors that cause wastages of carbon bush. The root cause for wastages were identified with helps of quality tools like (control chart, Pareto chart, cause and effect and diagram, etc). The major problem and cause that contributes for wastage which we assumed were through handling of work pieces (carbon bush), done by both machines and humans. The solution was generated after collection of various data through inspection.
