A gear machining controller capable of performing a gear machining of high precision. A gear machining tool and a workpiece are driven by a first motor and a second motor, respectively, to be synchronized with each other, to perform gear machining on the workpiece such as gear cutting and gear finishing. A position amending section is provided at least one of position control loops of servo systems for controlling position/velocity of the first and second motors. The position amendment section obtains amendment amounts based on position deviations and amends a position command of a present processing period by the amendment amount obtained at the processing period preceding by one cycle period of variation of a load torque. An error of synchronization of the first and second motors is reduced so that the gear machining of high precision is performed.
