Abstract: The industries have become more competitive in nature due to the technical research and development which made the industries to improve their productivity to meet their market demand. The industries started to invests more on machines for high productivity, but when the machine is not working properly then these machines has to be get repaired and it leads to breakdown hours and the manufacturers has loss in their productivity. So in this paper a solution has been suggested for reducing the break down hours of milling machine. This can be achieved by reducing the breakdown hours of the milling machines. Milling machine performs various machining processes like milling, grinding and boring etc. on the work piece. So to avoid this, Root-Cause Analysis of these defects is carried out and the modifications are to be done as per the results of analysis. Root cause analysis for milling machine is conducted to find the root cause of machine for breakdown time and some parallel improvement opportunities were also identified for implementation so as to reduce the breakdown time of machine. The project thus aims to minimize breakdown time and maintenance cost with maximum availability and profit, increase MTBF & decrease in MTTR. Finally to prevent the failure of equipment before it actually occurs.

Keywords: Root Cause Analysis, Preventive maintenance, Breakdown Reduction Methodology, Mean Time between Failures (MTBF), Mean Time to Repair (MTTR)
