Abstract (English):
As in the case of lathe machining, the problem of determining reliable values of the basic parameter such as cutting speed when working with CNC machines has been viewed. The necessity of preliminary diagnostics of contact pairs characteristics as a means of cutting process reliability control under conditions of indeterminacy of their physical and mechanical properties is indicated. The selection of processing conditions with autoatically-controlled method is described.

computational accuracy, contact pair, test run, reliability control of the cutting process, thermo-emf.
