In general, in finishing helical gears with modified tooth traces, it is necessary to consider an additional motion between the work and tool in the manufacturing process. In this paper, shapes of tooth surfaces of gears ground with the threaded wheel or profiled wheel with three kinds of additional motions between the work and wheel are shown by means of contour lines, and it is clarified that form grinding with the profiled wheel is the most suitable for finishing gears with three-dimensionally modified tooth surfaces. Moreover, a method of calculating amounts of the additional motions for 3-D tooth-surface modification when the approaching and excessive helical motions are used as a combination of the additional motions in form grinding is proposed. To demonstrate the usefulness of this method, the grinding tests of the helical gears were conducted on the CNC gear grinder. The shapes of the ground tooth surfaces were almost the same as those of modified ones in the design stage.
