N2 - According to the Taylor tool life equation, tool life reduces with cutting speed according to a power law. The relationship is quantified using an exponent, n, and a constant, C, which are tool-workpiece dependent. However, tool wear is also considered to be a stochastic process and difficult to predict. The Taylor tool life model is deterministic and there is inherent uncertainty in the empirical constants, n and C. In this work, Bayesian inference is applied to estimate the Taylor tool life constants using a discrete grid method. Tool wear tests are performed using an uncoated carbide tool and 1018 steel workpiece. The test results are used to update the beliefs about the Taylor tool life constants. The updated beliefs are then used to predict tool life using a probability distribution function.
