The materials mechanical properties are outlined in Table 2. The length and diameter of the parts used in the tests were 450 mm and 148 mm, respectively.
Grinding of tool steel - Bohler Uddeholm
GRINDING FORCES The grinding forces that act on each individual grain of abrasive are referred to as specific forces. A mean value of the specific forces can be obtained by dividing the total force by the number of cutting edges, which depends on the size of the contact area and the number of cutting edges in the grinding path. The specific forces determine

Coarse grain sizes are used for billet conditioning and snagging operations in steel mills and foundries, where stock removal rates are important and there is little concern about surface finish. Grinding wheel grade The grade of a grinding wheel is a measure of the strength of the bonding material holding the individual grains in the wheel.
Mill (grinding) - Wikipedia
A mill is a device that breaks solid materials into smaller pieces by grinding, crushing, or cutting. Such comminution is an important unit operation in many processes.There are many different types of mills and many types of materials processed in them. Historically mills were powered by hand (e.g., via a hand crank), working animal (e.g., horse mill), wind or water ().
