Overall Equipment Effectiveness Analyse for Performance of CNC Milling Machine Operation

Abstract

Overall equipment efficiency (OEE) is a large part of the maintenance system used by Japanese companies; Total Productive Maintenance (TPM). The value of OEE is affected by the often problematic production activities in machinery/production equipment such as damage to machine components resulting in reduced production, lowering engine production speed, preparation length and adjustment time, resulting in defective products and operating machines but not producing products. This paper will focus on the overall equipment efficiency of CNC Milling machine. The indicators of data parameter are used planned downtime, ideal cycle times, real-time cycles and daily operator reports (daily schedule controls) and direct data retrieval in the field. Where OEE calculation depends on availability, performance of efficiency, and rate of quality. The result has shown that the value of availability is 87%, performance of efficiency is 93% and OEE is 74%.
