The machine can talk, but it speaks in its own language. It communicates in the form of vibration. Imbedded in that vibration signal are all the internal defects of the machine. It is telling us about itself. All we have to do is listening. Sometimes, we need a translator. That is what the measuring instruments, especially FFT spectrum analyzer does. It translates the complex vibration signal coming from the machine into something that we, humans can understand. In machine diagnostics, we are playing the role of a machine doctor, which is not much easy task. Vibration signals are a major source of information available from the machine itself for fault detection and diagnosis. All factors should be considered, along with machine’s history, in any good diagnostic efforts. We are always looking at the effect to try to find the cause. This paper focuses on the understanding of machinery monitoring, sources of vibrations and. This paper tells us how to increase life of machine by arranging program of vibration monitoring and what are the precaution should be taken while analyzing any machine.
