The Quality Performances Improvement Using Failure Mode and Effects Analysis Method

摘要

Failure Mode and Effects Analysis (FMEA) method approach allows the implementation of specific procedures for improving the quality of products, processes or technological systems focusing on risk management within a system of classification of the severity and probability of potential failure. In the case study we propose to analyze potential failure modes specific to manufacturing process considering cutting tool, machine tool, measurement and control equipment. To analyze the results it is elaborated a Pareto analysis that is a technique for prioritizing possible failure modes and effects of failure by identifying the problems that will be solved by making the corrective actions. There are identified and assessed each corrective action taking into account the risk priority number (RPN) value after this implementation action and the feasibility of this under the existing constraints of cost, resources, and time, as well as quality and reliability requirements.
