The research on the machine-settings correction of spiral bevel gears used on the coordinate measuring machine is described.According to the basic tooth principle of spiral bevel gears,the theoretical equation of tooth surface is established,and the measuring grid is programmed.The calculating method of the errors of the real tooth surface on the normal direction is brought forward.The Sequential Quadratic Programming method is advanced to solve the overdetermined set of the machine tool regulation parameter and the normal error of the tooth.Some instances of real tooth surface measurement and machine-settings correction calculation are experimented on the coordinate measuring machine.It turned out that the technology and methods adopted in this paper is feasible.This study indicated that the method put forth in this paper has theoretical consequences and better applicable value in engineering.
