Chapter 3 Mechanics Of Grinding

The unit of the measure of attritious wheel wear is the ratio of total flat areas on the grains to the total wheel area taking part in grinding. The greater the wear flat area, the higher are the grinding force. But after a particular value of wear flat area, the rate of increase in grinding forces suddenly increases as shown in Figure 5.
