Comparative Experiment of Surface Roughness when Grinding 3X13, SKD11 and SUJ2 Steels with CBN Grinding Wheel

This paper presents the experimental study for comparison of surface roughness of work piece when grinding three types of 3X13, SKD11 and SUJ2 steels with CBN grinding wheel. The comparison methods in this study include comparison by means, comparison by numerical charts, comparison by histogram plot, and comparison by criteria's of probability theory. The results show that comparison by criteria's of probability theory leads to more reliability than other methods. On this basis, the values of surface roughness of 3X13 and SUJ2 steels are determined to be equal. Meanwhile, the surface roughness of SKD11 steel is much lower than that of the other two steel types.
