Abstract: An apparatus for manufacturing a blade is provided. The apparatus for manufacturing a blade includes: an arm module including a pressing unit pivoting around a first shaft; a molding module including a molding die pressed by the pressing unit and molding bulk metallic glass (BMG) to a blade; and a drawing module pulling an end portion of the BMG exposed to the outside of the molding die to form an edge of the blade, wherein the drawing module includes a pair of drawing tools pulling one end portion of the BMG in two directions.

Abstract: An atomizing cutting fluid system. The system includes a common chamber terminating in a shaped droplet nozzle and including a nozzle section immediately behind the shaped droplet nozzle. An atomizer creates spray directly within the common chamber behind the nozzle section. A cutting fluid supply line provides cutting fluid to the atomizer. A high velocity gas nozzle within the nozzle section and behind the droplet nozzle is configured to provide a high velocity gas to entrain the flow of droplets. The nozzle section and droplet nozzle are configured to produce a fully developed droplets-gas flow at a predetermined distance from the droplet nozzle. In a cutting system, the spray system provides a uniform film for a macro or micro cutting operation at sufficient flow rates.

Abstract: A high precision micro/nanoscale machining system. A multi-axis movement machine provides relative movement along multiple axes between a workpiece and a tool holder. A cutting tool is disposed on a flexible cantilever held by the tool holder, the tool holder being movable to provide at least two of the axes to set the angle and distance of the cutting tool relative to the workpiece. A feedback control system uses measurement of deflection of the cantilever during cutting to maintain a desired cantilever deflection and hence a desired load on the cutting tool.

Abstract: A micro-scale apparatus for supporting a tool for hard turning comprises a base, a pivot coupled to the base, an actuator coupled to the base, and at least one member coupled to the actuator at one end and rotatably coupled to the pivot at another end. A tool mount is disposed on the at least one member. The at least one member defines a first lever arm between the pivot and the tool mount, and a second lever arm between the pivot and the actuator. The first lever arm has a length that is less than a length of the second lever arm. The actuator moves the tool mount along an arc.
