摘要：
A method for designing root area geometry of a straight bevel gear providing reduced stress concentration and increased tooth strength. Also, a method for making a forging die for manufacturing gears having improved tooth root geometry. The method includes the steps of designing the straight bevel gear having improved root area geometry, designing an electrode for an electric discharge machining using CAD/CAM device, manufacturing the electrode, and manufacturing the forging die employing the electric discharge machining process.
