    • A disclosed example method for generating control data for forming a tooth of a spur gear toothing which has an intended widthwise crowning by milling a workpiece at a numerically controlled machine tool having at least 5 axes, at a universal machine tool, by successively moving a milling cutter of the machine tool along a plurality of machining paths based on the generated control data, involves providing a tooth flank geometry of at least one tooth flank of the tooth of the spur gear toothing. The method also involves determining parameters for specifying a change of the provided tooth flank geometry according to the intended widthwise crowing of the tooth. In addition, the method involves generating control data based on a tooth flank geometry which is changed based on the determined parameters, wherein the changed tooth flank geometry corresponds to a tooth flank geometry of the tooth having the intended widthwise crowing.
    • 一种用于生成用于形成正齿轮齿的齿的控制数据的示例性方法,其通过在万能机床上通过在万能机床上通过铣削具有至少5个轴的数控机床上的工件而具有预期的宽度方向的凸面, 基于所生成的控制数据,沿着多个加工路径的机床的切割器涉及提供正齿轮齿的齿的至少一个齿面的齿面几何形状。 该方法还涉及确定根据预期的宽度方向的搂紧指定所提供的齿面几何形状的变化的参数。 此外,该方法涉及基于基于所确定的参数而改变的齿面几何生成控制数据,其中,改变的齿面几何形状对应于具有预期宽度方向的挤压的齿的齿面几何形状。
