Increasing the Operation Rate of Punching Machine by Using ECRS

Abstract

The manufacturing industry is part of Thailand's economic system which has been continuously improved and developed for maximum benefit. The objective of this research is to increase the operation rate of punching machines in the metal punching process by collecting the machine usage data from the V-Factory program to show the operation rate of the punching machine. Brainstorming and a fishbone diagram illustrated the causes of the problem that affected machine downtime and the way to improve the process. Based on data, it showed that four punching machines had an average operation time of 5,191.65 minutes or 54.55 percent and machines downtime of 4,298.70 minutes or 45.45 percent. The cause of the machine downtime is due to improper raw material preparation. The researcher used the principles of ECRS to rearrange the workflow then designed the area for placing raw materials to reduce the time of preparing raw materials and prepared raw materials before production to increase the operation rate of punching machines. The results showed that the proportion of punching machine operation rate increased by 61.68 percent, or an increase from before improvement by 7.13 percent.
