The purpose of this study is to analyze the requisite conditions of grinding wheel topography for improving surface finish. In this report, a wide variety of wheel surface topography is examined with the previously developed simulation in which measured distribution of mounting spring constant, dimensional position and shape of abrasive grains are considered. The simulation makes clear that the necessity of wheel surface topography for the fine ground surface profile are to have the extremely small spring constant of grain mounting in a very top surface and its higher average and variation in the inner position from the wheel surface. In addition, to true up the grain edge position and to make a pointed edge of grains flat are necessary. The knowledge obtained from these analysis may be an important guideline in manufacturing, dressing and truing a grinding wheel.

In previous report [J. Japan Soc. Prec. Eng., 59, 3, (1993) 491.] under considering wheel surface topography and ground surface profile, it is theoretically predicted that a spring constant of grain mounting is extremely small in a very top surface of grinding wheel, and that the average of the spring constant and its variation become higher in the inner position from the wheel surface. In this report in order to make clear the displacement behaviors of abrasive grains during grinding process, the spring constant of individual abrasive grain mounting on the vitrified wheel surface are experimentally determined from the load-displacement curve of an abrasive grain measured by micro-Vickers hardness tester. The distribution of spring constant of abrasive grain is first analyzed and then it is made clear that the spring constant mentioned above can be predicted theoretically. And it is also made clear that the spring constant becomes to increase or decrease by steps as the elastic deformation or breakage takes place in the bond material.
