The Japanese introduced the concept of Total Productive Maintenance (TPM), in 1971 to overcome the maintenance problems. TPM is defined by Nakajima (Nakajima 1988) in Japan. Its main objectives are obtaining ideal performance, enhancing product quality, minimizing losses, and improving effectiveness of equipment.
In this paper experience of implementing Total Productive Maintenance is shared and investigated for a company manufacturing automotive component. Concept is implemented in the machine shop having CNC turning centers of different capacity. Overall Equipment Effectiveness is used as the measure of success of TPM implementation.

TPM is a powerful discipline leading, in a process of continuous, systematic improvement, towards the ideal, with 0 downtime, 0 defects and 0 safety problems. "Traditional" TPM (as created by Nakajima) is a set of participative programs designed to increase equipment effectiveness (productivity - quality - safety) and aiming at various goals:
Overview. One of the major goals of TPM and OEE programs is to reduce and/or eliminate what are called the Six Big Losses – the most common causes of equipment-based productivity loss in manufacturing.. First, let's define the Six Big Losses. Capture the Six Big Losses to gain additional actionable insight to the OEE Factors of Availability, Performance, and Quality.
Total Productive Maintenance (TPM) is a maintenance program which involves a newly defined concept for maintaining plants and equipment. The goal of the TPM program is to markedly increase production while, at the same time, increasing employee morale and job satisfaction.

Overall equipment effectiveness (OEE) is a measure of how well a manufacturing operation is utilized (facilities, time and material) compared to its full potential, during the periods when it is scheduled to run. An OEE of means that only good parts are produced ( quality), at the maximum speed ( performance), and without interruption ( availability).

Keywords:-TPM, Availability, Performance, Utilization, Overall Equipment effectiveness (OEE). I. INTRODUCTION Mining involves very costly and highly automated equipment for extraction of minerals, the size of the equipment and capacity has increased many folds in the recent past resulting in poor utilization and inefficiency of the machines.
Mining is the extraction of valuable minerals or other geological materials from the Earth, usually from an ore body, lode, vein, seam, reef or placer deposit.These deposits form a mineralized package that is of economic interest to the miner. Ores recovered by mining include metals, coal, oil shale, gemstones, limestone, chalk, dimension stone, rock salt, potash, gravel, and clay.

In the mining industry, both costs and equipment reliability have one significant thing in common -they are driven ... Total Productive Maintenance The prime objectives of TPM ...
in measuring overall effectiveness of equipments known as Ov erall Equipment Effectiveness (OEE). During 1980's, Total Productive Maintenance (TPM) has become known in manufacturing industries and OEE was proposed by Nakajima  to evaluate the progress of TPM. It is interpreted as the multiplication of availability, performance and quality.
