After the industrial revolution in the 19th century, the concept „quality‟ was borned with the competition in the products and services industry. That producers and consumers from past to present want to use the resources at an optimal level has contributed so much to the quality development. Because of global competition, the concept „quality‟ has gained much importance for the businesses to exist in the product or service market. The aim of this study is to sample the use of control charts which are the quality tools for increasing the levels of products or services. In the conducted study, in order to determine the level of aimed quality level, the control charts for variables (Shewart), cumulative sum quality control charts (CUSUM) and exponentially weighted moving average control charts (EWMA) are used. The differences among them are presented by using different control charts. The control chart for the copper industry will be helpful for the enterprise applications which will be held and theoretical studies
