The creation of new structural materials for manufacturing parts of various technical destinations is an integral part of modern industry, inasmuch as the requirements to products are mainly directed to the decrease of their mass, hardening, conservation of properties at the influence of hostile environment and temperature without attraction of additional expenditures for manufacturing. But, in the course of cutting a tool is worn out quickly and cannot ensure high efficiency of machining. The purpose of researches consists in the technological process efficiency increase of composite material edge cutting machining. As a problem of researches is the development of the procedure for the assessment of expenditures presented depending on the peculiarities of the tool design, its capacity for work and cutting modes. For the solution of problems set there is offered a procedure for the assessment of expenditures presented which takes into account the expenses for a cutter, work material, electric power and other parameters characterizing the techniques taking into account the specificity of composite material machining. There is an expenditure binding to empirical values of the technological period of tool life and machining productivity depending on cutting modes. The procedure is realized for the optimization of the technological process of composite material milling. The recommendation for the definition of cutting modes ensuring low expenditures for manufacturing is developed.
