Abstract

PT.XYZ  is a company engaged in manufacturing, focusing on the manufacture of molds and molds. In addition to mold and mildew manufacturing, the company also manufactures support machines in increasing production at other companies in the same group. With the increasing demand in the manufacture of molds, molds, and supporting machines, it turns out that the performance of the Fanuc Robocut -c400ib CNC Wire Cut machine is still less efficient with increasing demand, so companies have to find new ones. methods to improve engine performance, one of which is the implementation of Overall Equipment Effectiveness (OEE) which can be used to help calculate engine efficiency. In calculations,the OEE measures availability, performance, and quality. After making a study on the machine, it turned out that the CNC Wire Cut Fanuc Robocut -c400ib machine experienced high downtime, it was feared that it could slow down the production process where product demand from customers could not be completed according to the agreement. On the Fanuc Robocut -c400ib CNC Wire Cut machine the OEE value before research in December 2019 was 53.63%. Therefore, the authors focus on providing suggestions for improvements on the machine. The analysis used 4M1E, then the cause of the problem was searched with fish bones. The increase in OEE value is expected to increase the efficiency of machines that have high downtime.
