For cutting the composite lock gear with unequal tooth thickness, a study is made on the design method of gear sharper cutter with nonstandard parameter involute tooth profile and noninvolute tooth profile. The cutter tooth arrangement, the choice of teeth number of the cutter and the basic method of cutter design are discussed; and a new method of choosing deflection factor by using limited area is presented. And the curve of relationship between rear angle on tooth crest and helical angle on tooth side of the cutter is given so as to give a basis for the gear sharper cutter to choose its parameters. To design nonstandard gear sharper cutter by adopting the method mentioned above will simplify the calculation and will increase the efficiency of design.
