Condition based maintenance of machine tools—A review

• This paper presents the review of work presented by various researchers on instruments used for vibration measurement and signal processing techniques for condition monitoring of machine tools in manufacturing operations.
• It is concluded that there is huge potential for utilization of non contact instruments for vibration measurement in predicting the maintenance and failure aspects of dynamic machines.
• It is expected that miniaturization of the machine health monitoring systems will enable in the development of portable handheld devices.

During the operation, machines generate vibrations which result in deterioration of machine tools eventually causing failure of some subsystems or the machine itself. The vibration signatures analysis can be used to detect the nature and extent of any damage in machines and components or any maintenance decisions related to the machine. The condition based monitoring has become an important technique to ensure the machine availability by timely maintenance actions and reducing breakdown maintenance. This paper presents the review of work presented by various researchers on instruments used for vibration measurement and signal processing techniques for condition monitoring of machine tools in manufacturing operations.
