Risks Assessment Applied to Manufacturing Processes - Case Study

Abstract

The surface quality obtained by the manufacturing process depends on several factors determined by the particular cutting process. The task of optimization of design and making the process machining by one or more performance functions is very important. In this direction, between the simplest ways to make this optimization are: adapting the process parameters, optimization of constructive parameters of cutting tools, selection of working domain of cutting tools in accordance with the importance of performance criterions adopted to optimization. In this paper we are evaluate the risks using Failure Mode and Effects Analysis (FMEA) for a drilling process considering the equipment and measuring devices. The Process FMEA is used to identify the potential consequences of errors and omissions in the production process and develop the production control plan. In this respect, there are identified the factors that influence the manufactured products quality with emphasis on the interaction between failure modes and effects. Pareto charts are developed for specific potential causes of failure in order to determine and implement the methods of improvement, and the risks that have a significant impact on the manufacturing process, and every corrective action must be evaluated taking into account the expected risk priority value.
