Abstract. To manufacturing external threads apply thread-cutting the head with round combs, but there are certain difficulties at manufacturing exact grooves. The purpose of work - definition of influence of various factors on forces of cutting and accuracy of grooves for its increase. Experimental researches were carried out at threading grooves М27 with different steps. Laws of distributions forces of cutting and average diameters of grooves are received under various conditions of cutting, the proved correlation communication between fields dispersions forces of cutting and accuracy threading grooves is established, the corresponding equations of regress are received.
