Ti alloy has conventionally been used for parts of air plane or chemical equipment because it is lightweight and strong, and has a property of corrosion resistance. Furthermore, there are few allergies that are superior in living body cell fusion characteristics; is flexible, and have a characteristic to be flexible. These characteristics are most suitable for a dental implant or a total hip prosthesis, and a lot of Ti has been used. However, Ti alloy is a difficult-to-machine material. In this study, Ti was cut by some kind of tool materials such as single crystal diamond, cBN, tungsten carbide and CVD-SiC, and tool wear characteristics and surface roughness changes were evaluated experimentally.
