FEM simulation for the cutting of Ti-6Al-4V alloy was investigated. As for the constitutive law, the Johnson-Cook model that applied a reported parameters by Meyer-Kleponis was used. At the first, the calculated results were compared with the results of the cutting test such as the cutting force, cutting temperature and shape of chips. The calculated results for the cutting force, cutting temperature and the shape of chips nearly corresponded with the experimental results. The second, the cutting test using the restricted tools which reduced cutting force by shortening the contact length of the rake face of the tool and the chips was carried out. The cutting force was decreased as approximately 10%. These results showed that the computer simulation was effective for the design of the tool shape.
