Application of the averages and ranges method for the evaluation of the measurement system of an automotive component manufacturing company

Abstract

Objective: To evaluate the degree of reliability of the measurement system of a company that manufactures automotive components, guaranteeing the quality of the products supplied to its customers. Methodology: The development of the research is based on four phases: diagnostic evaluation, definition of methods and resources, development of the R&R and analysis of results. These studies were developed based on the MSA applying the method of means and ranges. Contribution: The results of the research determine that the current measurement system is adequate with respect to the processes analyzed, however, improvements are required to achieve the quality standards demanded by the automotive industry. Within the measurement system, 21.48% corresponds to the repeatability component, which is attributable to the measuring instrument; the reproducibility component has 5.818% and the GR&R interaction component represents 22.258%, which is within the standard recommended by the AIAG; however, this will serve as a basis for the company to orient its processes towards an improvement that allows a percentage of less than 10%.
