Abstract: This invention relates to devices used to measure the mass moment of inertia (MOI) of physical objects. Embodiments of this invention provide a compact device that is easy to use and adjustable to broaden the range of physical object sizes/MOIs that would not otherwise be measurable with a single nonadjustable device. The device protects certain components from being disturbed or damaged by the user by means of permanent attachment or affixment to the device, while still allowing the adjustability noted. While some parts, such as one or more auxiliary platters, must be fully attached and detached for the purpose of adjustment, other components of this specific invention remain permanently attached to the device to avoid loss or damage while still allowing them to be engaged/connected or disengage/disconnected for adjustment purposes.

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: The flow of heat energy from the cutting edge rim of a self-propelled round annular rotary cutting element (“insert”) to axial-load and radial-load bearings in a cartridge which rotatably supports the insert on a machine tool body is reduced by defining heat flow paths from the insert rim to cartridge components which engages the bearings to have low thermal conductance relative to heat flow paths from the insert rim to other parts of the cartridge. Control over heat flow path thermal conductance is obtained by selection of materials used between the insert rim and the mentioned cartridge components, by reductions in the cross-sectional areas of the critical heat flow paths, and by combinations of those two techniques. Protection of the bearings from heat enables the insert and the cartridge to be reduced in size. Improved mountings of insert-supportive cartridges to tool bodies are disclosed.

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.

Abstract: A milling tool includes a body which is rotatable about a first axis. At least one cutting tooth mounted on the body having a cutting edge for cutting about the first axis. A wiper tooth extends from the mill body. The wiper tooth includes at least at a portion having a peripheral surface about the second axis and the peripheral surface intersects a face surface defining a cutting edge that is round about the second axis for cutting about the first axis. In some embodiments, the peripheral surface, the face surface and the cutting edge are formed on an insert that is mounted the mill body.

Abstract: A face milling tool includes a body which is rotatable about an axis, at least one wiper tooth, and at least two primary cutting teeth mounted on the body having a cutting edge for cutting about the axis. The primary cutting teeth are staggered radially relative to each other by a radial shift so that a chip load variation during operation is less than 0.7 times a mean primary-tooth chip load. A method for determining the primary cutting tooth radial positions on a face milling tool body is provided such that a chip load variation during operation is less than 0.7 times a mean primary-tooth chip load.

Abstract: A wear surface system and method for preparing same. The wear surface system 10 has a substrate 12 with a surface 13 in which is defined three-dimensional, micro-metered prismatic anchoring sites 14. The sites include hairs that are separated by at least some spaces 16. To the textured surface 18 is applied a coating 24. The coating has substantially conforming three-dimensional features that mate with at least some of the anchoring sites. Upon solidification, the coating becomes hardened and is relatively immune from delamination due to internal and externally applied stresses during exposure to normal wear conditions. One method for improving the wearability of a surface comprises the steps of (1) providing a substrate; (2) texturizing its surface so that it is at least partially imbued with a three-dimensional, micro-metered, prismatic set of anchoring sites; and (3) coating at least a part of the textured surface with a mating coating that becomes hardened upon solidification.
