Profile Modification Technology of Involute Cylindrical Gear

In view of the problems existing in tooth profile modification process,based on slotting process which has high precision,this paper proposed a new method of using slotting cutter to achieve involute cylindrical gear profile modification.Modification curve is fitted by sub-involutes,the corresponding modification angles of slotting cutter are deduced,and the profile of modification slotting cutter is designed in this paper.
