To predict and enhance the cutting tool performance the primary requirement of the system is the efficiency of the model explaining the interactions at the tool chip interface. The predominating parameters which influence the development of the system are work piece material and machining variables or sometimes both. Further the development of low cost methodology to study the chip tool interactions with minimum amount of testing is of more importance. Major part of the work is emphasized on the investigation and characterization of various zones on the rake face of tungsten carbide inserts. Tests have been carried out by machining AISI 1040
