Simulation of Machining Errors Compensation of CNC Spiral Bevel Gear Grinding Machine

Abstract

Taking the eccentricity error of workpiece’s axis as an example, the real cutting pathes on the spiral bevel gear’s tooth surface and the normal errors were obtained according to each machining position. By decoupling error compensation motions, the compensation values of three translational and two rotational axes were obtained. After compensating, the tooth form errors were reduced largely. This compensation method is closer to the fact of gear grinding and the compensation effect is better than the method of adjusting machine setting parameters.
