Due to uncertainty in design, manufacturing and operating processes, the initial prediction of a machine’s useful life is often quite different from that of the actual machine. In this paper, we utilize the Bayesian technique to incorporate the fie

A variable tuned holder for machine tools that attaches to a machine tool to act in a manner similar to a dynamic absorber while the machine tool is used during machining. The natural frequency of the holder may be matched to the natural frequency of
