Development a machining method for single crystal diamonds has been investigated, as a result of the intense need of 3-D shapes of diamond. This processing method is achieved through utilization of diamond graphitization and tool wear of diamond during the cutting process of carbon steel. A three-dimensional shape of diamond has been successfully obtained by this machining method. In this study, a comparison has conducted among the present cutting method and other processing methods. At first, the present method is compared with a YAG laser machining; the diamond surface after machining by present method is much better than that by YAG laser machining method. Next, the present method is compared with other methods that utilize the affinity between diamond and ferrous material, using only heating or rubbing. The removal rate of diamond in cutting technique of this research is considerably higher and efficient than other methods. Some samples of the machined diamond by present method are shown in the end of this paper.
