Surface self-adaptive lifting method

The invention provides a surface self-adaptive lifting method, which relates to the technical field of workpiece heat treatment, and comprises the following steps: S1, determining model parameters, S2, creating a geometric model and carrying out grid division, S3, establishing a coordinate system in a geometric model set after grid division, S4, dividing a tooth surface of a large-modulus rack into three parts, continuously adjusting the movement speed of an inductor in each area, and carrying out surface self-adaptive lifting on the tooth surface of the large-modulus rack. And S5, a tooth surface path self-adaptive variable speed regulation method is adopted to complete the heating process of the deceleration area, the transition area and the acceleration area. According to the method, a tooth surface path self-adaptive variable speed regulation method is ingeniously used, the temperature consistency of the large-modulus rack is improved through intelligent regulation under the condition that the speed of an
