Vibration is the behavior of a machine's mechanical components as they react to internal or external forces. Since most rotating machinery problems show themselves as excessive vibration, we use vibration signals as an indication of a machine's mechanical condition. Also, each mechanical problem or defect generates vibration in its own unique way.

This phenomenon is commonly referred to as machine tool chatter (chatter vibrations) and, typically, if large tool-work engagements are attempted, oscillations suddenly buildup in the structure, effectively limiting metal removal rates.The structure again oscillates in one of its natural modes of vibration. It is important to limit vibrations ...

Aug 4, 2021As a rule of thumb, if the machine produces high amplitude vibrations (greater than 10 g rms) at the measurement point, a low sensitivity (10 mV/g) sensor is preferable. If the vibration is less than 10 g rms, a 100 mV/g sensor should generally be used.
