Abstract

The development stages of ultrasonic machine building technologies at National Polytechnic University of Armenia (NPUA) are introducted. It is shown that on the basis of scientific policy for the creation and implementation of promising technologies, existing in the USSR, according to which the development of the theoretical and experimental bases of new processes concentrated in academic institutions and universities, in 1967, by the decision of the State Committee of Science and Education (SCS and E), in Yerevan Polytechnic Institute after K. Marx (YrPI), under the supervision of the Academician of the USSR AS, Dr of tech. sci., Prof. M.V. Kasyan, a laboratory “Rheology of cutting” (PRC) was established. As a supervisor of the laboratory M-02 “Ultrasonic technology” in YPI was assigned a veteran of the great Patriotic War, a talented organizer and scientist, Professor M.E. Vardanyan, who rallied a team of young professionals and employees of
the Department “Technology of Mechanical Engineering”, and since 1968 - the new Chair of “Automation and Complex Mechanization of Mechanical Engineering”. Based on the resalution of the Republic of Armenia Government from 01.01.2005, at State EngineeringUniversity of Armenia (SEUA), a basic research laboratory “Engineering technology”(ET), which was the successor of the base laboratory of the PRC was organized. For half a century, the laboratory has had certain achievements in the field of research, design, development and improvement of the theory and practice of cutting materials with a cutting tool, including the ultrasonic methods and processing of materials by application of ultrasonic vibrations (ultrasonic testing), in particular: ultrasonic emulsification of
immiscible liquids, ultrasonic hardening of the working surface of machine parts by plastic deformation, creation of regular surface topography on the frictional surfaces of machine parts. The work summarizes the research activities of the laboratory. Based on the results in the key areas of the basic laboratory ET, since the day of its establishment, 2 doctorte and over 40 Master's theses have been defended, more than 40 copyright certificates and patents of the RF and RA have been received.
