研削面プロフィル創成シミュレーションから考察した砥石面トポグラフィの具備条件

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.
