Abstract: The paper presents a series of studies regarding the influence of the main constructive and cinematic parameters of the finishing-work hardening tools, on the durability of these tools and on the productivity of the manufacturing process. Thus, is studying the influence of the diameter of the rolling elements (balls) and the angle of the pressure cones "α" on the productivity of the machining, as well as the influence of the ratio between the pulsation of the rolling elements and the rolling speed, on the distribution of the unitary efforts, respectively on the durability of the tools used.
Brief Biography of the Speaker: Badea Lepadatescu is currently an Associate Professor at the Faculty of Technological Engineering and Industrial Management of Transylvania University of Brasov, Romania. He obtained his doctoral degree in 1998 in the area of machining through superfinishing process. After he graduated he worked five years as design engineer at Roman truck factory in the field of manufacturing processes where he designed many devices and special machine tools especially for superfinishing process. Started on 1982 he worked as research engineer at Transilvania University of Brasov, and after 1997 he is teaching at Department of Manufacturing Engineering. His main academic interests include Tolerance and Dimensional Control, Manufacturing Engineering Processes, Automation Processes, and Renewable Energy Sources. The research accomplishments are reflected through publications in a eight books and authored or co-authored over 130 papers published at international conferences. He has extensive experience in both experimental and theoretical research work having more than 50 contracts with factories to design and produce machine tools for machining processes. Also in the field of Renewable Energy Sources together with a team he made wind turbines, with horizontal axis for taking water, and with vertical axis to produce electric energy. He has been speaker to international conferences, has moderated forums, organized symposia, workshops and sessions at major international conferences.
