A tool and method for dressing a grinding warm that is to be used in forming a conical face gear that meshingly engages a conical involute pinion . The method employs a theoretical conical involute pinion as a reference to orient a dressing tool relative to the grinding worm at an initial position. A plurality of straight generators that define a reference tooth on the theoretical conical involute pinion and the concept of true conjugate action between the theoretical conical involute pinion, the grinding worm and the dressing tool are employed to define a plurality of dressing tool paths which are employed to position and move the dressing tool to form the teeth in the grinding worm. A method for grinding a conical face gear and a tool for dressing a grinding worm and forming a conical face gear are also provided.
