| Outline of Final Research Achievements |
The super elasto-plastic titanium alloy has stable mechanical property and superior biocompatibility. And also has low young’s modulus too. However, this characteristic is lost by severe heat environment and external force. Therefore, there is possibility that the advantageous characteristics may be lost during cutting. In this study, the effect of cutting temperature and cutting force on the affected layer was investigated by milling with small ball end mill tool. At the cutting speed of 16.0m/s, the thickness of the affected layer exceeded 2.5μm because of increasing of cutting temperature that approached to the neighborhood of transition temperature of this alloy. On the other hand, the affected layer was observed for the cutting condition of high cutting force by increasing feed rate of a tooth, depth of cut and pick feed, the thickness of the affected layer was 0.7µm .So, the affected layer was dominant by the influence of cutting temperature.
