Up to the present, aluminum alloy reinforced by short fibers of alumina is used as the parts of automobile because this material has wear-resistant. In the future, it is necessary to generate higher precision surface in order to apply to other uses. The purpose of this study is to experimentally generate higher precision surface of this material by means of diamond cutting with an ultra precision lathe. In order to attain the purpose, the first step was to quantitatively estimate surfcae roughness and defect from three dimensional measurement of the finished surface. After that, the optimum working conditions were selected. The results obtained from this study are as follows : The pore was generated by falling off of fiber, and the swell of matrix around fiber was observed in the finished surface. If tool geometry and another conditions were selected properly, better results were found to be obtained in surface defects, tool wear, and straightness of finished surface.
