Metodologia para Controle Estatístico de Processo em uma indústria de transformação de vidro

Abstract

The quality of products and services is a factor that adds competitiveness to the organizations, allowing some organizations to stand out. Quality assurance is a challenge for companies aiming at growth and maintenance in the market. In the search for better quality indices in obtaining products and services, the statistical process control (CEP) presents benefits in its use, making possible an efficient evaluation and monitoring of the process. The present work aims to develop and present a methodology for the implementation of Statistical Process Control (CEP) with Graph by attribute p, together with Sampling Plans based on standards NBR 5425, NBR 5426 and NBR 5427, for the critical industrial operations of lapidation and respectively, in a way that allows the achievement of goals set by management on a regular and constant basis, solving a problem in the quality sector of a glass processing industry. The work was produced through a qualitative expl oratory research, and the methodology developed from a literature review based on quality engineering, data collection, information on critical processes, collection and processing of data and information, as well as the elaboration and presentation of the same. The methodology has a plan divided into stages, where guidelines are drawn for the implantation of the CEP with chart p in the stoning sector, where special causes can be easily detected, as well as a presentation on how to use the standards, as well as the suggestion for application of the quenching process switching system.
