It is shown that when machining products from materials with heterogeneous structure, possibilities of management of a condition of a blanket are significantly limited. As an example of management, cutting processing of products from materials with heterogeneous structure – turning of high-strength ame evaporated coverings is considered. Because for an amorphous component of heterogeneous coverings the lack of deformation hardening is peculiar considerable deformation of the cut-off material is observed at their processing and characteristic shaving is formed. Highintensity thermobaric impact on the processed heterogeneous material leads to partial crystallization in a thin blanket with the high content of an amorphous phase. As a result of researches the criterion which quantitatively estimates the statistics, which complexly characterize uniformity of structure of materials and dispersion of their properties, is offered. The criterion allows defining ability of materials to be exposed to cutting without carrying out long experiments.
