In the research, wheel wear rate B and actual metal removal rate Z_<tp> were measured over a wide range of theoretical metal removal rate Z_<th>. By using the results, the grinding ratio G_B and the Z_<tp> in high-depth of cut grinding have been investigated mainly. The conclusions obtained are as follows : (1) At the Z_<th> within a critical theoretical metal removal rate(Z_<th>)_<cr>, the grain fracture is related to the B. At the Z_<th>, the B and the G_B do not show large variation for varying Z_<th>. And, the Z_<tp> is regarded as being approximately equal to the Z_<th>. (2) At the Z_<th> Over the (Z_<th>)_<cr>, the bond fracture is related to the B. From the (Z_<th>)_<cr>, the B and the G_B begins to increase and decrease steeply with the increase of Z_<th>. And, the Z_<tp> begins to become outstandingly smaller than the Z_<th>. (3) The (Z_<th>)_<cr> becomes larger for wheels of coarser grain and harder grade. Grain type in wheel influences the value of the (Z_<th>)_<cr>. (4) The Z_<th> from which Z_<tp> does not increase with the increase of Z_<th>, exists. (5) The sum of machining cost and wheel cost shows the minimum at a Z_<th> near the (Z_<th>)_<cr>.
