It is shown that the worn surface of a grit has a camber which causes decreasing depth of cut, leading to glazing. Orthogonal cutting theory is modified accordingly and equations are developed for rate of cut and for total metal removed. It is shown that erect grain orientation favors high rate of cut on mild steel but is not a major factor in rate of cut on stainless steel. It is predicted that decreasing the number of active grits will improve disk performance up to the point where dressing becomes excessive.
