Research on Simulation Algorithm of Spiral Bevel Gear's Virtual Manufacturing

Now the manufacturing of spiral bevel gears is going in digital virtual manufacturing direction, and virtual machining is a key link in digital manufacturing. Based on the spiral bevel gears meshing theory, the simulation algorithm is researched. Equation of Cutter and blank is established. Solving the gear tooth boundary points in the machine tool coordinate system, which is the key arithmetic of the tooth modeling With Delphi and OpenGL interaction techniques, the simulation environment is set up, including machining parameters and displaying interface, triangular patches to build the models for cutter, blank and the gears. The cutting process simulation is realized in real-time by analyzing of the NC codes, which can be independent of the existing commercial software
