The article presents the sequence of setting up an experiment to study the machinability of cutting alpha titanium alloys from the point of view of obtaining the required quality of the processed surface. The study is based on the hypothesis of the existence of a relationship between parameters that assess the state of the machined surface - roughness, microhardness and
residual stresses, with a minimum value of dissipation of the energy supplied to the workpiece. As a criterion for assessing the degree of dissipative processes arising in the material during cutting, it is proposed to use the coefficient of efficiency of energy dissipation, which is widely used in the theory and practice of metal working by pressure to determine the modes of stable plastic deformation.
