The prime objective is to maximise the uptime of machines and other equipment. Maintenance techniques have evolved over the years and have been adapted to various situations. Some programs are customised to maximise uptime. Others are designed to minimise the cost of spares while others are optimised to minimise human interference. The term maintenance is taken as the combination of technical, administrative and managerial actions that are taken throughout the lifecycle of equipment and machines. Broadly maintenance can be classified into two categories which are corrective maintenance and preventive maintenance.
Corrective Maintenance When a machine or equipment breaks down and maintenance is then carried out, it is known as corrective maintenance. Generally corrective maintenance has been the most extensive maintenance technique that has been applied throughout the years. Previously corrective maintenance was the preferred technique. . It was largely held that maintenance should be carried out when the parts of a machine or equipment complete their effective lifetime. This belief emerged as a solution to optimise the life of parts. The replacement of parts before need arose was not a highly preferred technique. However, as industrial enterprises expanded and competition arose, the need for maximising uptime increased. ...Show more
