Taking the process of two kinds of processing methods as research object

the process characteristic and advantage and disadvantage of cylindrical gear with curvilinear shape tooth are contrasted and analyzed.Based on the processing principle

machining process of two kind of gear is simulated by three-dimensional modeling software

and the three-dimensional model of the cylindrical gear with curvilinear shape tooth are obtained.The meshing analysis and interference analysis of two kinds of gear are carried out by three-dimensional modeling software.The analysis results show that

process performance of method of rotating knife dish is better than method of parallel connecting rod

especially finishing process of gear grinding and gear shaving can be used to machine the cylindrical gear with curvilinear shape tooth.So

the method of rotating knife dish for machining cylindrical gear with curvilinear shape tooth is more suitable for industrial application.It has a certain reference for the design and select of cylindrical gear with curvilinear shape tooth.
