An analysis of polymer materials behavior under cutting forces load was presented.The analysis was accomplished taking into account the existence and interaction of micro cracks in material.On the basis of modeling representations of a polymeric material behavior at cutting the method of preliminary mechanical destruction a superficial layer of polymeric material was developed.The essence of the method consists in producing micro-cracks in form of blind holes on the upper layer of blanks before turning.The aim of this method is a plastic deformation zones creation under stresses interaction occurring at the adjacent crack apexes.Results of experimental researches of fabric-based laminate turning processing according to the offered method were submitted.The analysis of the received results confirms expediency of application of the given combined method and the decrease of a roughness on the processed surface of fabric-based laminate is testifying about it.
