Abstract
According to a machining principle of the CNC gear hobbing machine, a functional relation between a geometric error of a gear and a tracking error of each motion axis of the machine tool is constructed; a machining error mathematical model of tooth profile deviation, tooth pitch deviation and tooth direction deviation at each position control time point is established by tracking errors of each motion axis; a compensation quantity required for a workpiece rotation axis at the next position control time point is calculated by establishing a decoupling compensation model; average absolute values of machining errors and a total compensation quantity of the machining errors under the conditions of not adopting the synchronous control method and adopting the synchronous control method in the total position control time are obtained by calculating machining error values of each position controls time point, and the synchronized multi-axis motion control is completed.
