Mar 13, 2007· Grinding Tips. It's a real pet peeve of mine to walk into a die shop or stamping plant and find a tool and die technician grinding on a large block of tool steel and leaving little black marks on the surface with each pass of the grinding wheel.
Grinding is a subset of cutting, as grinding is a true metal-cutting process. Each grain of abrasive functions as a microscopic single-point 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.) .
