Enhancement of Productivity and Efficiency of CNC Machines in a Small Scale Industry Using Total Productive Maintenance

Abstract:

Overall Equipment Effectiveness (OEE) of a machine plays a significant role in the present scenario, where right quality and right delivery at the right time are the major factors influencing a customer. The aim of this article is to study the effectiveness and implementing of an independent maintenance system in a machine shop for enhancing OEE with the help of Total Productive Maintenance (TPM) and 5S techniques using a systematic approach. This has been focused to minimize the breakdowns, increase the performance and quality rate of machines so as to improve the effectiveness. During this research discussion, reviewing of documentation and sequential records and direct observations were used as data collection methods. In this case study, increase in efficiency and productivity of machines in terms of OEE by implementing TPM in a machine shop are discussed. This research work deals with the aspects of availability, performance and quality which are used to calculate the OEE of a machine. The TPM techniques such as 5S, preventive maintenance and cleaning were effectively applied on the machine. The final result showed that the OEE improved by 5% in horizontal machining center and by 7% in vertical machining center.
