The object of research is the process of external rotary hard steel and alloy surfaces lathe turning with standard cutting tool using different lubricating and cooling technological means. The objective of this paper is to increase efficiency in external rotary hard materials surfaces lathe turning on the basis of optimal turning modes using relevant lubricating and cooling technological means. Methods of research. Theses of the metal cutting theory, mathematical modeling, and experimental methods, theses of technical mechanics, methods of linear programming and machining processes thermophysics have been used. The results received are of the following scientific novelty and practical significance: 1. Universal structure of technological process giving an opportunity to forecast new lubricating and cooling technological means efficiency developed in laboratory conditions without carrying out time-taking and expensive experimental works has been developed. 2. General method and algorithm for complex evaluation of new lubricating and cooling technological means during hard materials products lathe turning have been developed. 3. This paper gave an opportunity to develop pre-evaluation method for new lubricating and cooling technological means that provides for an opportunity to use these lubricating and cooling technological means correctly and reasonably for certain hard materials machining operations. 4. The results of the research have been introduced in OJSC Design Technology Institute (Ukraine, Donetsk), in the plant OJSC Universal Equipment (Ukraine, Donetsk), in Snizhne machine building plant OJSC Motor-Sich (Ukraine), in Donetsk National Technical University (Ukraine).
