A procedure for optimization of cutting modes taking into account a distribution law of cutter life as a random variable is presented. On the basis of the analysis of the optimization criterion – cost price as a function of the random argument there are obtained analytical dependences which allowed taking into account quantitatively cutter life spreading at its optimum value definition.
