Özet
In this study, the effects of cutting parameters on the surface roughness, burr height, hole-diameter deviation, cutting
temperature and structure of a chip formation were investigated during the drilling of the Ti-6Al-4V alloy. For this purpose, the
Ti-6Al-4V alloy was drilled at different cutting parameters, longitudinally in the 10 mm depth with Ø = 10 mm high-speed-steel
(HSS) drills, having 90°, 118°, 130° and 140° point angles on the CNC vertical machining centre. Experiments were carried out
at the (12.5, 18.75 and 25) m/min cutting speeds and the (0.05, 0.1 and 0.15) mm/r feed rates without using the cutting fluid. As
a result, as the feed rate and the drill-point angle were increased, the surface roughness increased as well; however, as the
cutting speed increased, the surface roughness decreased. When the feed rate and drill-point angle increased, the burr height
decreased. On the other hand, an increase in the cutting speed increased the burr height. In general, an increase in the feed rate
and drill-point angle increased the hole diameters, and the hole diameters obtained were close to the nominal size when the
cutting speed was increased.
