Early studies of the grinding process were based on the mechanics of an average individual grit on the wheel surface (Alden, Citation 1914; Guest, Citation 1915). Some aspects of the grinding process by which a grit grinds can be illustrated by the geometrical relationship between the grit and the workpiece during a grinding process.
