A worm gear tooth groove machining method comprises the steps that a five-axis machine tool is used, a worm gear forming disc milling cutter manufactured according to the sizes of a worm gear and a worm is installed on a machine tool spindle, and a worm gear blank is installed on a C-axis rotating table; setting an original point of a workpiece coordinate system as an intersection point of a central plane in the thickness direction of the worm gear blank and a central axis of the worm gear blank; the B-axis rotating table rotates until the included angle P between the central plane in the thickness direction of the worm gear forming disc milling cutter and the central axis of the worm gear blank is equal to the worm gear helical angle beta; the cutter location point is located at the point a0, then the cutter location point is fed to the machining path starting point a along the Y axis according to the cutting depth, and machining can be started; in the machining process, the main shaft drives the worm gear f
