INVESTIGATION OF THICKNESS AND BRIGHTNESS CHANGE WITH SHEWHART CONTROL CHARTS IN NATURAL STONE POLISHING PROCESS

DOĞAL TAŞ PARLATMA SÜRECİNDE KALINLIK VE PARLAKLIK DEĞİŞİMİNİN SHEWHART KONTROL GRAFİKLERİ İLE İNCELENMESİ

Abstract

In recent years, several studies have been conducted to reduce the defects that may occurduring the production phase with a view to ensure that the products introduced to the marketunder developing technology and competitive conditions meet the desired quality requirements.Statistical quality control is vital for the process of enhancing, improving and controlling theproduction phase. In this study, Shewhart control charts (the control charts for variables) areobtained for the purpose of identifying any potential change in the thickness and brightness valuesfor two different natural stone samples produced in the natural stone plant in Afyonkarahisar /Turkey. Statistical process control techniques, which play a key role in those quality studies,help businesses improve, enhance and control the production processes. Thanks to statisticalprocess control techniques, the problems experienced during the production processes could beidentified and the causes of those problems could be analysed to take action in order to preventrecurrence of the situation.
