Grinding (abrasive cutting) Wikipedia

Grinding is a subset of cutting, as grinding is a true metalcutting process. Each grain of abrasive functions as a microscopic singlepoint cutting edge (although of high negative rake angle), and shears a tiny chip that is analogous to what would conventionally be called a "cut" chip (turning, milling, drilling, tapping, etc.) [citation needed].
