Definition. Gear grinding is a hard finishing method for gears, using tools with a specific geometrical profile. It is divided into two main groups: generating grinding and profile grinding, relating to the manufacturing of the tooth flank. Furthermore, these groups can be subdivided into continuous and discontinuous processes (DIN 8589).
