    • Gear teeth of the gear being worked are machined by rotating the gear with a gear-type machining tool moved radially into tangential contact with the gear being worked. The relative of rotation rates of the gear and the tool are determined by the number of gear teeth in both the gear and the tool. The tooth width of the gear-type machining tool, which may be a worm gear, is less than the finished measurement of the tooth space of the gear being worked. When the gear-type tool reaches the prescribed manufacturing center distance, it is contiguous with the gear from one frontal face to the other. Two flanks of the gear are machined by feeding either the gear or tool in a direction perpendicular to the radial direction of movement so that the teeth of the tool can machine the gear tooth flanks as the gear and the tool rotate. First one flank of each tooth of the gear may be machined and then, by reversing the movement direction, the other flank of the tooth is machined. Alternately, both flanks of each tooth of the gear may be machined simultaneously by using two tools.
    • 正在加工的齿轮的齿轮通过使齿轮与齿轮式加工工具旋转而进行机加工,齿轮式加工工具径向移动,与正在加工的齿轮切向接触。 齿轮和工具的旋转速度的相对关系由齿轮和工具中的齿轮数量决定。 可以是蜗轮的齿轮式加工工具的齿宽小于被加工齿轮的齿隙的完成测量。 当齿轮型工具达到规定的制造中心距离时,它与齿轮从一个正面连接到另一个。 齿轮的两个侧面通过沿着与径向运动方向垂直的方向进给齿轮或工具来加工齿轮或工具,使得刀具的齿可以将齿轮齿面加工成齿轮并且工具旋转。 齿轮的每个齿的第一个侧面可以加工,然后通过反转运动方向,齿的另一个侧面被加工。 或者,可以通过使用两个工具同时加工齿轮的每个齿的两个侧面。
