摘要

The paper presents an analysis of the cutting tool structures for the destruction of frozen soils and snow-ice formations. The basic parameters (geometry and material) taken into account when creating cutting tools are revealed which are as follows: the influence of cutting speed on the durability of the cutting tool and cutting force, the optimal cutting angles and the layout of the cutters. The main advantages of using disc cutters in the design of ice-breaking equipment are presented. They allow you to replace the sliding friction of the cutting edge with the traditional rolling friction tooth (the disc rolls along the face). As a result, the tool life is increased, dynamic loads on the working body are reduced when meeting with the inclusions, since the contact of the cutting edge with the inclusions at the initial moment will be point, and the speed will decrease as it is immersed in the array, therefore, the load on the cutting tool will increase slowly.
