Abstract: This invention relates to finish machining, including a tool and the method of its use. Embodiments of this invention allow a cutting insert to be indexed quickly without loosening the insert retainer (screw or clamp) and not changing the depth-of-cut position of the tooth tip. The indexing motion is achieved by rotating a rotor, either manually or by way of a motor included on the tool. In some cases, between indexes, a small angle may be imparted to the rotor in order to adjust slightly the depth-of-cut position of the tooth tip in order to compensate for it being worn, or in other cases to precisely match the depth of cut of the tooth tips on multiple cutting teeth. The method involves setting up the path the tool will follow, then setting the feed per finishing tooth to be unconventionally large relative to the maximum depth of cut along the path.

Abstract: This invention relates to simple, compact rotary seals that contract to maintain a seal as the sealing elements may wear over time. Embodiments of this invention allow simple elastic rings, such as an O-ring, to be used as the sealing element.

Abstract: This invention relates to cutting tools used to machine materials to produce new surfaces and chips of removed material. Embodiments of this invention allow round rotating cutting inserts to be used in a more economical way, with improved accuracy, with improved sealing, and with greater ease of use. The rotary support device and cutting inserts may be used in either radial or tangential mounting types of cutters. It also provides a built-in, fully sealed means of fine adjustment of the cutting insert that is useful in some applications.

Abstract: A device for mechanically removing material from a workpiece or bulk feedstock, thereby creating chips of removed material while producing a new surface on the workpiece or bulk feedstock. The device comprises a body and at least one round cutting insert that is tangentially mounted on the body. Location and orientation of the insert is characterized by a reference plane offset and an insert axis angle. The insert has an outwardly-facing rake surface on which chips are formed. A planar flank surface is oriented relative to a cutting motion so as to provide clearance between the cutting insert and the surface created by removal of a layer that is converted into chips. A circular cutting edge lies at the intersection of the flank and rake surfaces.

Abstract: This invention relates to face milling tools used to create a generally planar/face surface on a workpiece. Embodiments of this invention allow more teeth per unit tool diameter for certain types of cutting insert mounting styles and generally for larger cutting inserts. In particular, this invention allows the aforementioned while keeping manufacturing cost lower than it could be with some other designs, mainly by allowing manufacture of the face mill using larger tools that approach the face mill from mainly or exclusively the axial direction, thus requiring the equipment used to manufacture the cutter body to be a lower cost three-axis machine as compared to four- and five-axis machines that may be otherwise needed. Embodiments of the invention also permit adjustment of the axial positions of multiple cutting inserts and their support pockets by way of adjustment in the face mill manufacturing process.
