摘要： A high-speed milling cutter (10) includes a shank (12), a front portion (14), and a transition surface (16) between the shank (12) and the front portion (14). The cutter (10) also includes an insert pocket (20) having a bottom surface (22) and side surfaces (24, 26). The bottom surface (22) includes a raised boss (28) for supporting a cutting insert (30). The cutting insert (30) has a top surface (32), a bottom surface (34) and side surfaces (36, 38, 40, 42). The cutting insert (30) includes a primary cutting edge (44, 46) formed at an intersection between the top surface (32) and two of the side surfaces (36, 38, 40, 42). The top surface (32) of the cutting insert (30) includes a concave or dish-shaped topography that is designed for high-speed milling operations of a metallic work piece. The cutting insert (30) also includes a bore (76) in the bottom surface (34) capable of receiving the raised boss (28) for securely retaining the cutting insert (30) within the insert pocket (20), and reducing bending moment on retaining screw 64 during high-speed milling operations.

摘要： A gear hobbing cutter system (40) that includes a cutter head body (42) having a plurality of cartridge-receiving slots (90) arranged in pairs comprising an inside and an outside cartridge-receiving slot (50A and 50B). Each pair of inside and outside cartridge-receiving slots (50A and 50B) are capable of receiving a respective inside and outside cartridge assembly (10A and 10B). To ensure that the inside and outside cartridge assemblies are properly positioned within their respective cartridge-receiving slots, one of the dimensions, preferably the length (LI or LO), of the inside cartridge-receiving slot and its respective inside cartridge assembly of a pair is different than the outside cartridge-receiving slot its respective outside cartridge assembly so as to form an error proofing system. A deformable area (58) is provided between the cartridge-receiving slot (50) and the cutter head body (42). The deformable area (58) includes a flex area (58a') for controlling an amount of deformation of the deformable area when a clamping member (46) bears against a clamping pad (56). The invention provides for a cartridge assembly (10) including a cutting insert (12) that can be indexable to at least two cutting edges, thereby providing cost savings as compared to conventional cutter systems that use cutter blades that required to be entirely scraped when worn or broken.
摘要翻译：一种滚齿刀系统（40），其包括具有成对设置的多个刀片架接收槽（90）的刀头主体（42），所述多个刀片架接收槽包括内侧和外侧刀片架接收槽（50A和50B）。每一对内侧和外侧卡盘接收槽（50A和50B）能够接收相应的内侧和外侧卡盘组件（10A和10B）。为了确保内外筒组件被适当地定位在它们各自的筒接收槽中，一对内筒组接收槽的尺寸（优选长度（L1或LO））及其相应的内筒组件不同于外部卡盘接收槽与其相应的外部卡盘组件，以形成防错系统。在盒容纳槽（50）和刀头主体（42）之间设有可变形区域（58）。可变形区域58包括挠曲区域58a'，该挠曲区域58a'用于当夹持构件46抵靠夹持垫56时控制可变形区域的变形量。本发明提供了一种包括切削刀片（12）的刀片架组件（10），所述切削刀片能够转位至少两个切削刃，从而与使用在磨损时需要完全刮削的刀片的常规切削器系统或破碎。

摘要： A multiple fluted helical end mill (10) with at least two flutes (20-26). Each flute includes a plurality of inserts (38) secured therein. The inserts (38) are all identical. The inserts (38) in different flutes (20-26) being secured therein at different rake angles ( alpha . beta ). The different rake angles ( alpha . beta ) resulting in different effective axial lengths (EAL) of the inserts. This different effective length of inserts in adjacent flutes results in all effective cutting and it is particularly beneficial where the inserts in a given flute do not have overlapping cutting edges.
摘要翻译：具有至少两个槽纹的多槽螺旋端铣刀。每个凹槽包括固定在其中的多个插入件。刀片都相同。不同凹槽中的插入件以不同的前角固定在其中。不同的前角导致插入件的有效轴向长度不同。相邻凹槽中插入物的这种不同的有效长度导致所有有效的切割，并且在给定凹槽中的插入件不具有重叠的切割边缘时特别有利。
