This is a second progress report on a long-term research project on precision grinding. The relationship between specific energy and rate of metal removal—reported previously—is confirmed, and the study is extended to examine the effect of wheel hardness. As a result, there is some modification to the interpretation of this relationship. The pattern of wheel wear is related to the corresponding pattern of grinding forces. Surface finish throughout the run is shown to be dependent upon wheel truing and depth of cut, and to deteriorate as the run progresses following wheel truing to spark out.
