摘要： A cutting tool for a milling, drilling or turning machine has a body with a plurality of sides and a central opening. Each side has a perimeter along which cutting planes or edges are formed. Each side has at least two such cutting planes or edges. The planes may have a straight or curved profile, or a combination of straight and curved profiles along one side. The tool may have a plurality of such cutting planes formed along each side of the tool body. The cutting planes may be located at different levels in relation to each other, entering a work piece in sequence, or may be aligned to enter the work piece simultaneously. Preferably, the cutting planes are staggered in two directions—in a feeding direction and in a cutting direction. By dividing each surface being cut into a plurality of segments, the cutting tool creates a plurality of distinct shavings, or splinters that have shorter length in comparison with conventional splinters formed by indexable tips. Shorter cuts require less cutting force, which saves wear on the cutting tool and the machine. At the same time, the cuts can be made deeper and smoother when dividing the cutting surface into a plurality of segments.

摘要翻译： 用于铣削，钻孔或车削机床的切削工具具有多个侧面和中心开口的主体。 每一侧都有一个周边，形成切割平面或边缘。 每侧具有至少两个这样的切割平面或边缘。 平面可以具有直的或弯曲的轮廓，或者沿着一侧具有直的和弯曲的轮廓的组合。 工具可以具有沿着工具主体的每一侧形成的多个这样的切割平面。 切割平面可以相对于彼此位于不同的水平位置，顺序地进入工件，或者可以对齐以同时进入工件。 优选地，切割平面在进给方向和切割方向上沿两个方向错开。 通过将被切割的每个表面划分成多个段，与由可转位尖端形成的常规碎片相比，切割工具产生多个不同的切屑或碎片，其具有较短的长度。 较短的切割要求较少的切割力，从而可以节省刀具和机器的磨损。 同时，当将切割表面分成多个段时，可以使切割更深更平滑。
