rotational speed (500, 1000, and 1500 rpm) and feed rate (40, 60, 80 mm/min). The

results revealed that maximum temperature increased as the feed rate increased

from 40 up to 80 mm/min. But, the in situ temperature decreased when the feed rate

increased above 80 mm/min. Temperature-induced during bone drilling is positively

correlated with spindle speed. Most signicant parameter found to be directly fol-
