Tool life and Surface finish of the part are the key considerations during machining. This research aims to precisely calculate the temperature rise and temperature variation trend during drilling of pure aluminum blocks to a specific depth under varying cutting conditions. The thermal rise due to friction occurs at the multiple cutting edges during shear interaction between cutting tool and work piece were investigated using non-contact infrared temperature sensor. A 10mm End Mill cutter of High-speed steel coated with titanium is used for drilling in Aluminum blocks using conventional universal milling machine. A series of experiments were conducted for different nine combinations under varying tool speeds(43, 77, 141 rpm) and feed rates (0.53, 0.97 and 1.94 mm/min) during dry drilling to a drill depth of 10mm. Each combination is tested for two samples for statistical analysis and results authentication.
