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.

On the basis of experiment results there is carried out an analysis of the cutting parameter impact upon force components of cutting at processing composites with cutting edges under different cutting conditions. The analysis of circular graphs of force components of cutting reasoning from the specified role of each force in the course of cutting is carried out.

Differences in results of metal and composite machining and also the technological parameters impact upon results of machining are considered. Fracto-graphic peculiarities of chip surfaces obtained after different polymeric composite blanks machining, and front faces of cutting tool edges are shown. The results obtained will help to assess physical model potentialities at polymeric composite blank cutting.

The peculiarities in polymeric composite material cutting are considered. The recommendations for use of different materials for cutters, their geometry and treatment modes are offered that allows obtaining the required quality of a product surface.
