In Metal Turning, Influence of Rake Angle on Cutting Tool Life.

In order to reduce the production time and energy loss which is being wasted to re sharp the tools when they got blunt during machining, hence in accordance to this problem, in this research work the effect of rake angles on tool life has been studied. The various rake angles used are, 0°, 1°, 3° and 6° while and while the other parameters like depth of cut, feed rate, cutting speed, clearance angle were kept constant. All the experiments were carried out on mild steel with High Speed Steel (HSS) as cutting tool. It was found that the tool having rake angle of have maximum tool life.
