ドレッシングにおける砥粒切れ刃の形状分布

抄録

Property of the working surface of dressed grinding wheel is evaluated in term of the shape distribution of grain edges. The distribution, which is obtained by optical measurement of grain edge shapes, is greatly affected by grain material and dressing conditions; feedrate as well as dresser infeed can adjust it when the sharp dresser is used, while feed rate hardly change the dullness of grain edges when the worn dresser is used for fine dressing of GC wheel. Next, shape transition of grain edge due to collision with dresser is analyzed as a Markov process. The transition probabilities among the edge models is calculated and the effect of feed rate on the distribution is examined quantitatively.
