In grinding processes, the maximum undeformed chip thickness is one of the most important parameters as in machining processes. Conventionally, in order to estimate the maximum undeformed chip thickness in grinding operation, it is necessary to obtain the successive cutting point spacing by experiments. Based on the material balance using average grain model, it is possible to estimate the maximum undeformed chip thickness without using any experimentally obtained data. The validity of the proposed analysis has been verified based on two sets of grinding scratch tests using W A and CBN grinding wheels.

As a new approach to analyze grinding characteristics, this paper introduces a specific grinding energy model based on the surface area of grain. Using this model, specific grinding energy were investigated with changing grinding variables. From the experimental results, the specific grinding energy is analyzed with both maximum undeformed chip thickness and grain size.
