Spiral Bevel Gear Manufacturing on a CNC Five-Axis Machine using Bell-Type Milling Cutters
Considering flexible manufacturing of bevel gears in small and medium batch size,five-axis machine center is another good option compared with the dedicated bevel gear cutting machine.Company Heller in cooperation with company Gleason offers a new solution for bevel gear cutting on its five-axis machine tool.Here,a bell-type milling cutter with indexable inserts replaces the special face-milling cutterhead.However,it did not disclose the details of such application due to commercial considerations.The main goal of this paper is to establish a mathematical model of spiral bevel gear using a mill cutter on a five-axis machine center.First,a virtual machine is proposed to provide movements between the cutter and the work gear.According to the position and normal vector of the mean point on the imagery generating gear,the position of cutter relative to the work gear is determined.And then,conversion from the virtual machine enables derivation of the nonlinear coordinates of the CNC five-axis machine.Finally,flank topographic errors are evaluated by comparing produced tooth surface with the theoretical one.And the correctness of the five-axis tool paths is confirmed using VERICUT NC simulation software.
