    Abstract: A thread milling tool includes a proximal shank portion and a distal cutting portion. The cutting portion includes at least one thread milling tooth and at least one flute oriented helically, or spirally, about a central rotational axis of the tool. The cutting portion may be configured to form internal or external threads in a workpiece as the cutting portion moves relative to the workpiece. The teeth of the thread milling tool have a negative taper angle or back taper to offset deflection of the tool during milling operations.

    Abstract translation: 螺纹铣刀包括近端柄部分和远端切割部分。 切割部分包括至少一个螺纹铣削齿和至少一个以工具的中心旋转轴线为螺旋状或螺旋形的方向。 切割部分可以被配置为当切割部分相对于工件移动时在工件中形成内部或外部螺纹。 螺纹铣刀的齿具有负锥角或后锥形,以抵消在铣削操作期间刀具的偏转。

    Abstract: Worm wheels are formed from cylindrical blanks mounted on opposite sides of a cutter in the shape of a worm with a tapered end fluted to provide cutting edges. The cylindrical blanks are keyed or splined on parallel shafts fixed to corresponding worm wheels engaging on opposite sides of a worm. The cutter and the worm are driven concurrently and the cutter is advanced between the cylindrical blanks to cut teeth in the peripheral surfaces thereof.

    Abstract translation: 蜗轮由安装在切割器的相对侧上的圆柱形坯料形成,其形状为具有锥形形状的蜗杆形状,以提供切削刃。 圆柱形坯料被键合或花键固定在与蜗杆相对侧啮合的相应蜗轮上的平行轴上。 切割器和蜗杆同时被驱动,并且切割器在圆柱形坯料之间前进,以在其圆周表面中切割齿。
