碩士 === 國立成功大學 === 機械工程研究所 === 82 === This thesis investigates the grinding characteristics of chromium-molybdenum alloy steel with the vitrified bonded CBN (cubic boron nitride) and Al2O3 wheel. The grinding forces, surface roughness and wheel wear were measured under various grinding conditions, and an optimum grinding condition was obtained. Using the 3-axis machining center, dynamometer and surface roughness testing machine, the grinding force and the surface roughness of the specimem under various grinding conditions for both alumina oxide and cubic boron nitride wheel. The experimental results showed that te grinding performance with cubic boron nitride is superior to that with alumina oxide. Based on the experimental results of this study, an optimum grinding condition was applied to the grinding of variable pitch lead screw with conical meshing elements. Then, the surface quality of the screw was measured.
