Machinability becomes one of major factors for designing high-performancestructural materials. In general, higher strength or higher toughness of a material poses some difficulties of machining. Some free-cutting additives are contained in a structural material to make machinability high. It is, however, difficult to determine how much they should be contained in designing a material. A FEM cutting simulation has high predictability. It can predict the cutting forces, the cutting temperature, the surface integrity and the tool wear, if the material properties of the workpiece and the tool and the cutting conditions are known. Then, this study aims to develop a material design system that utilizes a FEM cutting simulation. This paper shows some simu-lation results of cutting of inhomogeneous materials, and discusses the adaptability of material design of the FEM cutting simulation.
