review text: Summary: The time-variant reliability and its sensitivity of cutting tools under both wear deterioration and an invariant machining condition are analyzed. The wear process is modeled by a gamma process which is a continuous-state and continuous-time stochastic process with independent and nonnegative increments. The time-variant reliability and its sensitivity of cutting tools under six cases are considered. For the first two cases the compensation for the cutting tool wear is not carried out. For the last four cases the off-line or real-time compensation method is adopted. While the off-line compensation method is used, the machining error of the cutting tool is supposed to be stochastic. Whether the detection of the real-time wear is accurate or not is discussed when the real-time compensation method is adopted. The numerical examples are analyzed to demonstrate the idea of how the reliability of cutting tools under the invariant machining condition could be improved according to the methods described in this paper.
