At present polymeric composite materials (PCM) substitute more and more wider metal in various branches of mechanical engineering. But the mechanical engineering of such materials with an edge tool causes considerable difficulties, as it differs in principle from common steel and alloy machining. A significant factor in choice of cutting modes and tool application and, as a consequence of a chip forming at PCM machining is a fiber orientation taking into account a cutting direction. The paper reports the results of researches in edge working by different tools with antifriction coal-plastic.

Main performance indicators of grinding wheels are the strength and wear resistance of abrasive grains. The description of the installation for studying the process of micro-cutting of various materials with single abrasive grains, which allows you to approximate the working conditions of a single abrasive grain to the conditions of real grinding in a wide range of cutting speeds. The effect of the cutting speed on the maximum cut thickness maintained by the grain vertexes without their destruction is shown. The influence of physical and mechanical properties of the workpiece material and the abrasive tool material, together with technological factors, on the micro-cutting process is considered.

Tool materials used for polymeric composite blank machining, kinds of tool material wear arising at machining these blanks, and also the impact of technological parameters upon tool wear are considered. The obtained results allow estimating the potentialities of physical models at polymeric composite blanks cutting.
