PERFORMANCE RATE DATA ANALYSIS OF OEE BY DATA RECORD SYSTEM MODIFICATION IN FINAL INSPECTION MACHINE

Abstract

The role of machinery is crucial in production to keep it optimized. The capacitor manufacturing process consists of assembly and final inspection. Analysis of the final inspection improvement shows that the decline in machine performance is caused by the repetition of inspection which causes lost time and affects the daily production time. The cause of detection errors is unpredictable and still unknown. This research measures the performance of machines in the manufacturing industry with the Overall Equipment Effectiveness (OEE) method and uses 7QC tools such as fishbone and flow charts. After the project was completed, it was found that the decline in the performance of the final inspection machine was due to a lack of focus in the analysis. The limited data after the final lot made it difficult to determine cameras with high inspection errors because inspection repetition data was not recorded. In this study, data from 10 manual inspection lots on each machine were taken, the average impact of re inspection was 14.1%, and the average performance after re-inspection was 81.6%. Camera 3 has the highest number of defects at 34% and camera 4 at 29%. The higher the number of camera defects, the greater the performance degradation in the inspection process.
