The new design of the face milling cutters with wedge cutters, fixed to the face milling cutters on a flexible rod of the segment of the wire rope. The parameters of interaction face milling cutters with destructible road ice area near curbstone roads and city streets. The determining factors are the thickness of the road ice (20 ÷ 120 mm) and the velocity of the road sweeper, of 0.5 ÷ 2 km/h. Determinable parameters of the cutter are: width of the wedge cutter, angle cutter axis, milling performance, the total moment of forces of resistance to cutting, shaft power cutters. Were obtained equations of calculation of working parameters cutters. Uneven load ratio when the angle of inclination of the axis of the cutter 2 to 42 degrees is reduced from 4 to 1.8. At the further increase of the angle of inclination of the axis milling uneven loading on the cutters increases again. For temperatures from -5 to -15 degrees specific resistance to cutting road ice for optimal conditions is 180 N/m. Coefficients of the accounting of unevenness of a course of the car, heterogeneity of structure, temperature and height of a layer of road ice are presented.
