ANALISIS KINERJA ALAT BANTU PENGUKURAN PANJANG INSERT DALAM PEMBUATAN ULIR UNTUK PULLEY SHAFT

Abstract

Every activity of producing goods is likely to result in defective products and damaged products caused by several factors. Supervision of production results is needed to reduce the number of defective and damaged products. In addition, the quality control analysis process will have an impact on the company's reputation and increase consumer confidence in the company's performance, the manufacture of pulley shafts must be produced with great care to produce excellent product quality. To avoid the number of defective and damaged products that occur, an analysis of each process must be carried out, which aims to quickly find the root causes of product defects and make improvements to eliminate or minimize ongoing defective products. The analysis was carried out using the Fishbone diagram method, namely analyzing the Man, Machine, Method, Material sections. Based on the results of the analysis of the research data, product defects that occur in the effective diameter of the thread occur due to differences in the length of the insert cutting edge for the screw feeding process in the manufacture of pulley shafts. So an improvement was made by making production aids to measure the length of each insert. The measurement results refer to the master insert that was made before, so that the deviation value is obtained which will be input into the program. Performance analysis is carried out on measurement tools so that they can assist in an effective and efficient production process. From the results of analysis and research, it was found that this measurement tool is very helpful in the insert replacement process so that it can reduce the number of defective products produced after replacing the insert eye or a new insert.
