Based on NC machining theory, the basic principle of iso-base bevel gear is expounded, and the modification method of tooth line and tooth profile of base curve gear bevel gear, such as finger milling cutter, is proposed. The design principles and design parameters of the finger milling cutter are derived.The tooth surface equations and tooth root transition surface equations which are included in the modification of the tooth line and the tooth profile are deduced. The tooth line of the iso-base bevel gear is a special curve whose concave- Traditional curve bevel gear tooth line of the opposite direction of the concave and convex, you must use CNC machining; profile milling cutter profile modification can be achieved gear along the theoretical tooth line can be achieved by moving the cutter tooth line modification; by Tooth line and tooth profile combination of modified tooth surface to achieve the shape of tooth surface curvature analysis, meshing analysis and strength calculation laid the foundation
