Abstract: Cost of the product along with the quality of the product is of prime importance sustaining in the market among the consumer. Product cost comprises of several component in which one of the components is manufacturing cost. There are several components in the manufacturing cost and tool cost one of them. A tool will have some initial cost which is fixed but effect of tool cost on over all machining cost depends on tool life. Longer the tool life lesser the impact of tool cost on overall machining cost, and hence lesser the product cost. There are several parameters affects tool life which are not going to be considered here. In the present work effect of coolant temperature is considered on tool life. Coolant is supplied at different temperature while machining for a fixed period of time and keeping all other machining parameters fixed every time corresponds to different temperature. The study shows the lower the coolant temperature higher the tool life.

Keywords: Tool life, tool wear, coolant, tool productivity.
