Although the demand for industrial applications for brittle material growing rapidly, the manufacturing of brittle material for making precise components is very challenging due to its poor machinability and brittleness. In this chapter, theoretical analyses are given based on brittle material’s mechanical properties as the functions of temperature and on critical conditions for ductile mode chip formation in cutting of brittle material. An energy model for ductile mode chip formation in cutting of brittle material is developed, in which critical undeformed chip thickness for ductile chip formation in cutting of brittle material is predicted from material’s mechanical properties, or tool geometry and cutting conditions used. Experiments are conducted on conventional grooving of tungsten carbide material to verify the proposed model for predicting critical undeformed chip thickness, which shows a substantial agreement between the predicted value and experimental results.
