Abstract: A process by which nanostructured monolithic bodies can be produced in a single continuous operation, as opposed to multi-stage deformation processing. The process generally entails continuously producing a chip having a nanostructured microstructure by engaging a solid body with a cutting edge of a tool while the solid body and the cutting edge move relative to each other, and simultaneously extruding the chip in the immediate vicinity of the cutting edge, such as with a constraining member, as the chip is separated from the solid body by the cutting edge to continuously plastically deform the chip and produce a nanostructured monolithic body immediately downstream of the cutting edge. The shape and size of the chip can be simultaneously controlled by the extrusion process so that the nanostructured monolithic body has a predetermined geometry. The nanostructured monolithic body can be in the form of a product suitable for immediate use, or undergo further processing to yield a product.

Abstract: A precision tool holder for precisely positioning a single point cutting tool on 4-axis lathe, such that the center of the radius of the tool nose is aligned with the B-axis of the machine tool, so as to facilitate the machining of precision meso-scale components with complex three-dimensional shapes with sub-?m accuracy on a four-axis lathe. The device is designed to fit on a commercial diamond turning machine and can adjust the cutting tool position in three orthogonal directions with sub-micrometer resolution. In particular, the tool holder adjusts the tool position using three flexure-based mechanisms, with two flexure mechanisms adjusting the lateral position of the tool to align the tool with the B-axis, and a third flexure mechanism adjusting the height of the tool. Preferably, the flexures are driven by manual micrometer adjusters. In this manner, this tool holder simplifies the process of setting a tool with sub-?m accuracy, to substantially reduce the time required to set the tool.

Abstract: A method for manufacturing a mechanical seal used in fluid applications, wherein the mechanical seal is comprised of a sintered (cemented) tungsten carbide ring that is turned on a lathe at a negative top rake angle instead of formed by grinding. The cemented tungsten carbide ring is initially prepared by rounding corners of the top surface to form a radii. The resulting mechanical seal yields significantly less surface damage, can be formed using faster cutting speeds and feeds than when grinding, enables formation of a greater range of complex geometries for the mechanical seals, and requires fewer passes than grinding. The compact is also formed at a significantly reduced cost as compared to grinding.
