In order to evaluate the mechanical properties of chemical vapor deposited diamond plates, the diamond plate has been applied to cutting tool. A diamond film of 20mm in diameter, 1.2mm thick was synthesized by arc discharge plasma jet CVD.This CVD diamond plate was shaped into a cutting edge by YAG laser irradiation and the polishing method using heat-chemical reaction with hot metal plate. After shaping, the polished diamond that has the nose radius roundness of 0.5 um was brazed onto a shankCutting of aluminum alloy was conducted to evaluate the performance of this CVD diamond cutting tool. The CVD diamond cutting tool was evaluated in terms of wear and chipping of the edge, shape and surface roughness of workpiece, the shape of chips. As a result of the experiments, it is found that the CVD diamond cutting tool can be used for ultraprecision cutting and has sufficient strength to cutting of aluminum alloy because the CVD diamond cutting tool shows almost the same wear charcteristics as a single crystal diamond cutting tool

为了评价化学气相沉积金刚石板的力学性能，将金刚石板应用于刀具。采用电弧放电等离子体喷射CVD法制备了直径20mm、厚度1.2mm的金刚石薄膜，并将该金刚石薄膜用YAG激光照射和与热金属板热化学反应抛光的方法加工成切削刃。加工后，将刀尖圆度为0.5 μ m的抛光金刚石钎焊在刀柄上，进行了切削铝合金的实验，以评价该CVD金刚石刀具的切削性能。对CVD金刚石刀具的刃口磨损、切屑、工件形状和表面粗糙度、切屑形状进行了评价。实验结果表明，CVD金刚石刀具具有与单晶金刚石刀具基本相同的磨损特性，可用于超精密切削，对铝合金的切削具有足够的强度
