چکیده انگلیسی
This work aims at studying wear and its inherent mechanisms, which are present during the process of machining Ti6Al4V alloy, using PCD (Polycrystalline Compact Diamond) tools under superfinishing conditions set within the following environments: cryogenic (liquid N2), hybrid (liquid N2 + fluid at minimal quantity of lubricant - MQL) and flood (vegetable fluid). The machining process was performed under the following conditions: feed rate 0.01Â mm/rev, depth of cut 0.1Â mm and cutting speed 240Â m/min. The results obtained show that the flank and crater wear was of dominant wear shapes. Adhesion followed by the plucking out of hard diamond grains and their movements over the tool rake face produced the abrasive wear, these were also observed in flood conditions.
