Abstract In the generation of agile manufacturing, the machines and its functions are also becoming complex. OEE of a machine plays an important role in present scenario where delivery and quality are of prime importance to customer. The paper reports a case study for improving OEE with help of TPM and 5S techniques using a systematic approach. The present aimed at minimizing the breakdowns, increasing performance and quality rate of machine thus improving the effectiveness. Initially the machine history was analysed which helped in finding the bottleneck machine. The OEE was found to be 43% in the identified bottleneck machine. Further, a TPM team was formed to devise a systematic approach to improve the effectiveness. The project has been addressed in three aspects; namely Availability, Performance and Quality which quantify OEE of a machine. The TPM techniques such as Preventive Maintenance, Cleaning with Meaning, Pokayoke & Kaizen were effectively applied on the machine. The result obtained from the TPM approach showed that the OEE was improved from 43% to 72% which indicated the desirable level in al manufacturing industry. To sum up, total saving per annum due to increased effectiveness was around Rs 4, 53, 000/-. Top Keywords Overall Equipment Effectiveness (OEE), TPM, SOP, Kaizen, Pokayoke and 5S. Top |
