Disclosed is a numerically controlled method of broad application but particularly useful for grinding cutting edges and clearance surfaces on cutting tools such as end mills and other similar tools. A programmable numerical servo-motor type control is described. All of the grinding operations are completed at a single station in a series of consecutive grinding operations performed by the same grinding wheel and during which the tool remains in the same work holder. The various cutting edges and clearance surfaces to be ground are both mathematically located and mathematically defined such that the grinding operations may be conducted under numerical control according to optimum wheel speed, feed, position and coolant conditions and with a wide range of independently and simultaneously movable axes. A grinding wheel wear compensation program and a coolant dispensing program are also numerically controlled in coordination with the grinding operations.
