A Probabilistic Tool Life Equation in Machining Optimization

A probabilistic tool life equation, which can accommodate the non-linear dependence of tool life on cutting conditions in the logarithmic plot, is proposed. The tool life is assumed to have a log-normal distriburion. The influence of both the tool life scatter and the required reliability level are taken into account. It is shown that the conventional machining optimization based on the deterministic tool life equation, when in fact the tool life is a random variable, yields incorrect results.
