Investigations on failures of production machines through risk management and maintenance engineering for loss reduction

Abstract

With an increase in the interest in automation and mechanization newlinethe machine maintenance in manufacturing field has become more important newlinethan ever The attainment of higher degree of quality maintenance ensures the newlinequality of the product Whenever machines fail to attain maintenance standard the risk of producing defective products increases This phenomenon demonstrates the existence of a strong link between machine maintenance and product quality At the same time excessive maintenance would result in unnecessary expenditures whereas poor maintenance would lead to defectives and breakdowns Hence it is essential to carry out maintenance engineering activities effectively at minimum cost and at the same time without compromising the quality of the product In this context maintenance engineering in manufacturing field was selected as a broad area of research work This research work was carried out with the scope of improving the performance of production machines through the reduction of failures and associated losses During this research literature survey was conducted to investigate the research works already carried out in maintenance engineering area with the focus on cost reduction Deficiencies in the previous research works in this field were identified and defined as the research problem Thrust activities in maintenance engineering area which influence the scope of the research were identified for investigation A maintenance model named Responsive Maintenance Model encompassing quality maintenance risk management and engineering principles was designed Case studies were conducted in thrust activities by applying the RMM newline
