Abstract：To design a curvilinear cylindrical gear with arbitrary tooth surface contact pattern,a method for determining the radius of a disc-shaped milling cutter for machining the curvilinear cylindrical gear was pro-posed based on the reverse determination of the required dimensions of the contact pattern.Firstly,the mathe-matical model of the tooth surface of the curvilinear cylindrical gear was introduced.Secondly,a mathematical model for calculating the contact patterns was established.Then,taking four curvilinear cylindrical gears ma-chined by double-edged milling cutters with different radii as examples,the relation graph between the radius of the disc-shaped milling cutter and the contact patterns was studied.Finally,the radius selection of the disc-shaped milling cutter was achieved through interpolation.This method can skip the gear trial processing,reduce the manufacturing cost of gears,and lay the foundation for the design and manufacturing of fixed-setting face-milling curvilinear cylindrical gears.
