ABSTRACT FMEA is used during the design stage with an aim to avoid future failures. The following presentation explains the changes that can be made in the present quality management system. The procedure requires the identification of all potential failures, causes of those failures and effects of those failures. FMEA is used during the design stage with an aim to avoid future failures. If something goes wrong it will effect the final product supplied to the customer. This article shows the use of FMEA as a prevention tool in the designs. A group of employees were trained in prevention tools, they designed the process map, identified the critical points and applied the FMEA method in order do prevent any failure during the design operation.The first results indicated that all the actions implemented were really effective in preventing errors. We have taken up this project as quality management today requires high expertise which changes with time and technology. We are doing this project on valves in Rane Engines Valves Limited. The first results indicated that all the actions implemented were really effective in preventing errors. Based on the data obtained, the FMEA was revised and new actions were established in order to obtain the defect-free product and that the customers were satisfied with service they have... 2

INTRODUCTION The most demanding part of the technique is identifying the likely causes of failure (failure mode) in a design, product or system. Once failure modes have been identified, a Risk Priority Number (RPN) is calculated based by assigning probabilities to the above factors, on a scale of 1 to 10. Guides to assigning scores are available. Corrective action is then taken according to the RPN priorities. In FMEA, Failures are prioritized according to how serious their consequences are, how frequently they occur and how easily they can be detected. An FMEA also documents current knowledge and actions about the risks of failures, for use in continuous improvement. FMEA is used during the design stage with an aim to avoid future failures. Later it’s used for process control, before and during ongoing operation of the process. Ideally, FMEA begins during the earliest conceptual stages of design and continues throughout the life of the product or service.Traditionally, reliability has been achieved through extensive testing and use of techniques such as probabilistic reliability modeling. These are techniques done in the late stages of development. The technique helps identify failure potential in a design or process i.e. to foresee failure before it actually happens. This is done by following a procedure which helps to identify design features or process operations that could fail. The procedure requires the identification of: All potential failures.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
