Higher cutting ratio denotes that the cutting action is good. l 1 = length before cutting l 2 = length of chip after cutting b 1 = width of chip before cutting b 2 = width of chip after cutting α = rake angle of tool β = shear angle The volume before cutting is equal to the volume after cutting., the volume of metal cut off from workpiece equal to the volume of the chip.

In fact, an ideal grinding condition (IGC) was observed with this combination. Ideal conditions are when the grinding efficiency remains unchanged (or in this case actually improves) with increasing metal removal rates (Q´). It was previously considered impossible or contrary to scientific principles for this to occur in grinding operations.

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 are many different types of mills and many types of materials processed in them. Historically mills were powered by hand (, via a hand crank), working animal (, horse mill), wind or water ().
