Abstract

Overall Equipment Effectiveness (OEE) is a tool use for measure the performance of the machine or equipment via availability, performance, and quality. The purpose of this project is to improve the OEE of stamping machine via implementation of Single Minute Exchanges of Die (SMED). The stamping process is the core process in the company that face long setup time, frequent breakdown occur that causes delay in running the machine. These kind of problem can contribute to big loss in term of cost and time to the company. Three objectives of this project are (i) identifying the stamping machine that has lowest OEE performance, (ii) implement the SMED for improving the OEE performance, and (iii) validate the SMED for improving the OEE. Two stamping machines with lowest OEE performance are used in this project which are 110T (A) and 200T compared with other machines. Video recording are required to record the changeover process of the stamping machine. The comparison of OEE performance between current and after SMED implementation are made. The result shows that the total changeover time of the stamping machine 110T has been reduced from 7.08 minutes to 10.88 minutes while stamping machine 200T is reduce from 28.37 minutes to 19.71 minutes. The SMED implementation has improved the OEE performance of machine 110T from 62% to 87%, while for the machine 200T OEE improved from 52% to 94%. As a conclusion, the implementation of SMED can improve OEE performance of stamping machines through the reduction of changeover time.
