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).

摘要： A multiple fluted helical end mill with at least two flutes. Each flute includes a plurality of inserts secured therein. The inserts are all identical. The inserts in different flutes being secured therein at different rake angles. The different rake angles resulting in different effective axial lengths 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： A milling cutter with tangentially mounted cutting inserts includes cutter pockets that are arranged at one end of the cutter body such that the screws for retaining the inserts generally radiate from the cutter's center. The cutter pockets are designed to secure a generally rectangular insert with eight or less cutting edges. The number of inserts and corresponding flutes vary as a function of the diameter of the cutter body. For example, four inserts with corresponding flutes are mounted on a 1.25″ diameter cutter body, and three inserts with corresponding flutes are mounted on a 1.00″ diameter cutter body. The increased number of flutes provide for increased metal removal rates and higher feed rates, as compared to an inserted ball nose mill or end mill. The cutter pockets are angled such that there is sufficient clearance under the insert cutting edges and present a “reverse lead” so the cutter assembly can produce a slightly undercut profile on the workpiece, or fixturing of almost five degrees so the radius generated on the workpiece can be nearly the same as that generated by a ball nose mill. The cutting inserts include facets for generating very good surface finishes on the workpiece.

摘要： An end mill type rotary cutting tool and associated cutting inserts that collectively compensate for radial pocket runout, thereby eliminating overlap marks in a machined work piece. The tool has pockets arrayed in helical flutes such that after one insert has abraded the work piece, a subsequent flute makes an overlapping pass. The inserts are so mounted in the cutting tool and have curved corners configured such that no degree of pocket runout due to manufacturing tolerances will cause any portion of the cutting edge of any insert to form an incuse cut in the work piece which penetrates the machined surface by more than the manufacturing tolerance. Thus overlap of inserts eliminate outward projections in the machined work piece and dimensions and configuration of the inserts and their pockets eliminate inward gouges, thereby eliminating visible overlap marks in the work piece.
摘要翻译： 端铣刀式旋转切削刀具和相关联的切削刀片，其共同地补偿径向凹坑跳动，从而消除加工的工件中的重叠标记。 该工具具有排列成螺旋槽纹的凹口，使得在一个插入件磨损工件之后，随后的长槽形成重叠通过。 插入件被安装在切割工具中并且具有弯曲的角部，使得由于制造公差而没有程度的口袋跳动将导致任何插入件的切割边缘的任何部分在穿过加工表面的工件中形成切口 超过制造公差。 因此，插入物的重叠消除了加工的工件中的向外的突起，并且插入件的尺寸和构型及其凹口消除了向内的刨削，从而消除了工件中可见的重叠痕迹。

摘要： A gear hobbing cutter system that includes a cutter head body having a plurality of cartridge-receiving slots arranged in pairs comprising an inside and an outside cartridge-receiving slot. Each pair of inside and outside cartridge-receiving slots are capable of receiving a respective inside and outside cartridge assembly. 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, 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. In addition, the invention provides for a cartridge assembly including a cutting insert 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.
