The assembly type formed milling cutter is widely applied in manufacturing complicated curve surface because of its advantages of adjustability and changeability. The problem of designing an assembly type formed milling cutter is how to design the edge curve. We analyzed the geometric property of edge curve of formed milling cutter, deduced the curve's mathematics equation, got the center coordinate of disc blade, and designed the edge curve by CAD. The rim section sketches of engine wheel that were trimmed by the assembly type formed milling cutter are up to the mustard. And the work efficiency to trim the rim section sketches by this cutter can be improved two more times than by traditional turning.
