A mathematical model to estimate the average number of parts, processing which is possible to achieve the criterion of maximum allowable wear on the back of the cutter heavy lathe, and the maximum allowable amount of tool material, removed from the front surface of the tool. Experimental equipment for measuring tool wear has been developed. Insert wear curves derived from industrial test results. Confirmation of the adequacy of the models of the instrument gives a possibility of their adjustment to the basic criteria of their dullness.
