1. Introduction
Supplying quality products in bulk and in short period of time requires high speed machining. Many problems caused
during machining are due to the heat generation and the subsequent high temperatures associated with it. Increased cutting force, excessive tool wear, poor surface finish, poor dimensional stability, etc. are temperature dependent side effects which are also interdependent and are the major concerns in metal cutting industry (Boothroyd, 1985). These high cutting temperatures can be controlled by profuse cooling with conventionally used coolant. But the problems associated with conventionally used coolant are (Anon, 2001):
