Considerations about the influence of lubricant in different machining mechanical processes

Abstract

Abstract. There are numerous researches that highlight the fact that wear related processes of machine components are one of the main causes which leads to their destruction. The main reasons for wear are related to the initial state of contact surfaces described by mechanical and physical properties of their superficial layer. Thus friction surface's state depends on previous mechanical machining done on this surface especially the last one. This study presents a method which proposes and creates premises for a microgeometry favorable to maintaining the lubricant on part surfaces for as long as possible dependent on different machining processes. Comparisons are made between values specific to the wear state of the considered part obtained by various machining by measuring material mass removed during functioning in similar working conditions.
