Polzunov Altai State Technical University, 46 Lenina avenue, Barnaul, Altai region, 656038, Russian Federation Abstract The article discusses the process of grinding composite materials. The workpiece is a composite material. A method of manufacturing a workpiece is the oblique longitudinal cross-winding. The cutting process is a end milling. There are many features of milling composite material: large tool friction on the workpiece, high temperature, high wear. Wear affects the type of chips. Can be three types of chips: chip shavings, fine chip, dust chips at the same time. The predominant type of chips depends on the state of the cutting blade. The cutter blade may be new, to have normal wear, have a critical wear. Influence of wear of blades of the cutting tool on process of formation of a shaving is studied. Experimental studies have been carried out. The cutting force, the amount of wear of the cutting blade, the type of chips were measured. Graphic and analytical relations for calculation of values of values of wear of cutting forces of the prevailing type of chip are made. The presented results will be used for CAD/CAM systems for designing operations of mechanical processing of composite materials.
