REDUÇÃO DO REFUGO NO PROCESSO: estudo de caso da variabilidade no comprimento de um perfil de vedação através do controle estatístico de processos – CEP

Abstract

This work analyzes the possibilities of waste reduction in the process in an automobile company, through some tools of the Statistical Process Control methodology. Global competition forces organizations to look for highly efficient and waste-free manufacturing processes. On the face of it, such an approach is justified by the concern to create competitive advantages in a market full of highly qualified competitors, in which optimization of productive processes becomes paramount for organizations to remain competitive in today's marketplace. The purpose of this research is to demonstrate the reduction of scrap in the process, analyzing the variability of the length of the car sealing profile, through some tools of the Statistical Process Control methodology. This article is based on a bibliographical review with theoretical basis and later on in the construction of a case study, carried out through the data collection, in which MINITAB® SOFTWARE 17.0 was used to generate statistical graphs. The research showed some problems, among them, the non-controllable causes, which made it difficult to study the variability of the profile length. However, with the help of the process capability tool indices, it was possible to control process variability, reduce costs and estimate parameters, providing competitiveness and profitability for the company.
