Abstract
One of the most popular titanium alloys used in manufacturing industries is titanium alloys with 6% of aluminium, 4% of vanadium and Extra Low Interstitial and also known as Ti6Al4V ELI. Titanium alloy is developed widely in many manufacturing industries because of its prominent characteristics namely high strength-to-weight ratio and good biocompatibility with human body. This research aims to analyze burr mechanism of titanium 6Al 4V ELI which was machined by using micro milling method in dry cutting condition. Machining trials were conducted at selected condition of milling parameters which are spindle speed of 10.000 and 15.000 rpm, feed rate of 0.001 and 0.005 mm/rev, depth of cut of 100 and 150 μm and diameter of cutting tool of 1 and 2 mm. The form and type of burr were observed under Scanning Electromagnetic Microscope (SEM) for each machining process according to the selected parameters. This method was done to identify the burr at both sides (left and right) of cutting groove. The results showed that the diameter of cutting tool was the most significant factor effected on burr formation. The use of bigger diameter of cutting tool produced serrated, smaller and shorter burr formation. Machining at 1 mm of diameter of tool and depth of cut of 150 μm resulted long formation of burr and tight serrated. Contrary, the use of cutting tool diameter of 2 mm and depth of cut of 100 μm generated short and slight burr formation.
