Complete the equivalent conversion of machining parameters for spiral bevel gears using the full process method, and express the motion axis in the form of a sixth order polynomial, improving the ability of tooth surface correction; The correctness and accuracy of the conversion are verified, providing technical support for the numerical control machining of high-precision spiral bevel gears.
A two-sided collaborative correction model for tooth surface error based on the sixth order polynomial coefficients of the moving shaft is established, and the amount of correction parameters is increased. The selection of weight coefficients is used to achieve tooth surface error correction to reduce tooth surface error, which proves the effectiveness and feasibility of this method.
The method of correcting tooth surface errors by adjusting polynomial coefficients in the full process machining of spiral bevel gears is also applicable to other machining methods.
