Inorderto analyze in the shaving process of shaving cutter and the shaved gear geometric relations,expressing the whole tooth surface of gear shaving cutter tooth profile,the standard involute gear tooth surface and method to correcting surface superposition way to represent tooth surface of gear shaving cutters,and presents the calculation method ofradial shavingcuttertooth surfacetopologytoothprofile. Firstly,accordingtothegear meshing principle design and calculate the tooth surface equation of the plunge shaving cutter;secondly, through the inverse algorithm tocalculatethe modification surfaceprocessing,repair ofradial shaving cutter tooth cylindrical gear profile modification;finally,through calculating the effect of cases of comparative a- nalysis ofgear
