Abstract:

To evaluate the contributions of total productive maintenance (TPM) initiatives to improve manufacturing performance in the machine shop. Due to frequent failures and breakdowns occurred in machine, require more investment on maintenance due to which increased in maintenance cost and this results into different losses at work place which cause low availability, poor performance and low quality of the output ultimately cause low OEE of the machine. The correlations between various TPM implementation factors and manufacturing performance improvements have been evaluated and validated by employing overall equipment effectiveness (OEE) in machine shop. OEE of a machine plays an important role in present scenario because it provides the information about the effectiveness of the equipment.Results obtained through the detailed study reveals the varying trends in the Overall Equipment Effectiveness (OEE) and Total Productivity of the machines taken up for the study. The average values of OEE were found to lay between the ranges of 49% to 61%against world class standards of 85%. The results highlight the major causes resulting in the downtime and decrease in the productivity. In this paper, a comparative study between World Class industries where TPM has been implemented and industry which do not follow TPM identifies the various problems leading to decrease in the overall efficiency of the industry and provides valuable suggestions for the improvement and methodology for implementing TPM pillars in industry.
