Abstract: To improve the machining accuracy of unilateral gear grinding in processing gear by forming method, a calculation method for sensitive direction of grinding wheel eccentricity error to profile error was proposed. Based on helicoid forming principles, the contact line between formed grinding wheel and tooth surface was solved, so the formula of wheel profile and tooth profile could be derived. According to the fundamental nature of involute profile, the profile normal error after processing raised by grinding wheel eccentricity error was calculated, and the effect of grinding wheel eccentricity's sensitive direction and insensitive direction on this error was discussed. VERICUT computer simulation was used to verify the proposed calculation method, and the result could help the design of CNC form grinding machine.
