It is well known that a diamond tool will be worn severely when cutting process is performed to ferrous material by a diamond tool. The purpose of this research is to develop a three dimensional micro machining method for a diamond by utilizing this phenomenon. The experiment is conducted by a lathe, where a ferrous material rod is fixed at the chuck of the lathe, and a single crystal diamond is fixed on top of a shank in the tool post of the lathe. A screw pattern is given to the external surface of the ferrous material rod and the feed rate during cutting process is made into the same value as the pitch of the screw. By this process, the pattern of screw can be transferred on the diamond surface. From the above experiments, the following conclusions can be obtained.1.A diamond can be machined by this method 'irrespective of the crystallographic orientation.2.The removal rate of diamond is the largest in (1,1,0) plane, and it is the smallest in (1,1,1) plane.3.The cutting temperature degree during the process is effective on the removal rate of diamond.4.The machined surface by this method is much better than that one by YAG laser machining. The machining removal rate by this method is better than that by other rubbing method.5.The process of this machining is investigated by measuring the cutting force, the machining temperature and the actual depth of cut.

金刚石刀具在切削黑色金属材料时，会产生严重的磨损。本研究的目的是利用此现象发展一种钻石的三维微细加工方法。实验是在车床上进行的，在车床的卡盘上固定一根铁质材料棒，在车床刀架的刀柄上固定一颗单晶金刚石。在黑色金属材料杆的外表面上设置螺旋图案，并使切削过程中的进给速度与螺旋螺距相同。通过这种方法，可以将螺纹图案转移到金刚石表面。从以上实验中可以得出以下结论：1.金刚石无论晶向如何，都可以用这种方法加工; 2.金刚石在（1，1，0）面的去除率最大，在（1，1，第一章3.加工过程中的切削温度对金刚石的去除率有影响。4.用这种方法加工的表面质量比传统方法好得多。YAG激光加工的。通过对切削力、切削温度和实际切削深度的测量，研究了该方法的加工过程。
