In this study, a drilling experiment was conducted on titanium ASTM B265 Grade 2 material using PVD coated carbide inserts. Two types of coolants (Wet and LN 2 ) were used. The variables in the experiment were feed rate (f) and cutting speed (V c ). The depth of the drilling was constant. Cutting temperature (T), thrust force (F t ), surface roughness (R a ), and the hole quality (circularity, cylindricity, and perpendicularity) were analyzed. The tool wear and chip morphology were studied. The result of the experiment indicates that there is 6-59% reduction in cutting temperature when LN 2 is used, high thrust force values were recorded for LN 2 coolant condition, surface roughness (R a ) values were higher for LN 2 coolants. Hole quality is not favorable in LN 2 coolant supply.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
