Industry 4.0 Applications And Digitilization Of Lean Production Lines

European economy faces two main problems in manufacturing sector: inefficient production with high costs and long time to supply new products to market. With these obstacles, economies cannot compete with other developing countries like China. In order to overcome these problems, leading firms works on new paradigms like lean production, digitilization and industry 4.0. Firms could simplify production lines by dealing with all the wastes, delays, faults etc. through the workplace. So they can shorten the production cycle times, data entry time, waiting semi-finished products, faults and scraps in the production lines. Industry 4.0 applications helps lean manufacturing lines to realize more efficient and quality production sytems. Because, these applications will make the European economy grow increasing productivity and added value of the products. In today’s industry digitization is vital for manufacturing processes. Especially in automotive supplier industry getting data from the machines and production lines by digital panels and monitors is vital for efficient production. Rim industry is one of the suppliers of automotive manufacturers. In order to provide quality and high performance products in time, rim producers try to apply lean manufacturing systems and industry 4.0 applications to their production lines. Jantsa is one of the biggest rim producer of Turkey with 200 diffrent sizes and over 3,000 different designs and models. The factory is located on 95,000 square meters area with the production capacity of nearly1,900,000 wheels annually. They expert 75 % of these wheels to over 80 countries worldwide. The digitilization project realized in Jantsa aims to get information about the rim production lines and make necessary improvements in order to increase efficiency. The name of the project is Production Data Collection and Barcoded Product Tracking Automation. OEE (Overall Equipment Effectiveness) calculation method is used in order to digitilize production lines in lean systems for improving processes. According to test data we have three factors effecting OEE calculation: availability, performance and quality. When we make the calculation the test results of OEE is 93.1%. It is fairly high according to international production standards. The focus should be on increasing the performance of machines and equipment used in the operation.
