Abstract: The step being performed in a state where a wheel body is fixed to be prevented from rotating around a rotation axis while a cutting edge of a cutting tool is in contact with the three-dimensional shape surface of the design surface in the wheel body, the cutting tool being three-dimensionally and continuously moved relatively along the three-dimensional shape surface while being changed in direction with respect to the three-dimensional shape surface to allow a rake face of the cutting tool to face a tool travel direction to perform three-dimensional continuous cutting processing that allows a specular glossy surface to be automatically formed in the three-dimensional shape surface, the specular glossy surface being finished into a processed surface having a high metallic gloss property by exposing the base metal.

Abstract: A sculpting machine, a method of sculpting a work-piece and work-products produced therefrom are described. A sculpting machine provides a cutting tool holder that is configured to hold a cutter in contact with a work-piece and move in two or more planes or axes of controlled motion about the work-piece to remove material. The cutter is non-spinning and is held in contact with the work-piece to carve away material, or sculpt the work-piece. The cutter may be held against the work-piece with the cutter in a fixed orientation relative to the surface of the work-piece being cut. The cutter may be moved along a straight line, curve or arc. The resulting product produced may have a much tighter tolerance and smoother surface finish than products machined with conventional techniques.

Abstract: An apparatus (100) and method (200) of contact machining having applications in profiling operations utilizes at least one static cutting tool (101) and turret (102) driven by rotary motion (103) about a support mechanism (109) for providing sufficient force to achieve deformation by controlled fracturing (523). This allows the separation of material from a workpiece (105) without imposing axial symmetry upon either the cutting tool (101) or the workpiece (105). The apparatus and method mitigates and/or eliminates the adverse effects of plastic deformation (504) while machining a wider range of shapes and materials with greater productivity and precision than existing methods of machining.

Abstract: A microscopic geometry cutting device includes: a controller that outputs a timer count start command in starting a driving program which controls a drive of an X-axis or a Y-axis moving mechanism; an arrival time calculator that calculates an arrival time from when the timer count start command is output till when the cutter arrives at a machining start position in accordance with relative moving speed information of the moving mechanisms and machining start position information of a workpiece W; an elapsed time determiner that determines whether an elapsed time from when the timer count start command is output is coincident with the arrival time and outputs a trigger signal when the elapsed time is coincident with the arrival time; and a reciprocating stage driver that drives the reciprocating stage in a manner that the cutter advances and retracts in a predetermined cutting depth in response to the trigger signal.

Abstract: A material cutting machine has a tool mount support mounted for reciprocal movement and a tool mount supported by the tool mount support. A driver, such as a pneumatic cylinder, selectively advances and retracts the tool mount support. A control system is operatively coupled to the driver for setting the advancement force of the tool mount support when a tool supported by said tool mount contacts a workpiece, such as the edge or surface of a moving strip. In this way, the depth of cut of the tool is controlled by tool advancement force rather than by accurate positioning of the tool. In one embodiment, the tool mount support may have a head and a base and a resilient member resiliently coupling the head to the base to provide a damped resilience. With this embodiment, a transient spike in the reaction force which may result, for example, from a hard spot in the material, causes the tool to momentarily deflect.

The Y axis is driven and the tool is moved toward the workpiece a predetermined amount, and the above-described scan is performed.

Abstract: The illustrative embodiments provide a method, apparatus, and computer usable program product for generating datamatrix barcodes on parts. A digital datamatrix code associated with a machined part on a numerically controlled machine tool is converted into an x-y drilling pattern contained in a numerically controlled program. A drill cycle associated with a numerically controlled program defines a pattern of dots to be drilled in the machined part to form a dot pattern. A dot pattern is drilled as a series of partially drilled holes on a surface of the machined part to form a datamatrix barcode mark.

Abstract: An elliptical vibratory cutting apparatus includes a control mechanism which applies a sinusoidal voltage having a predetermined phase difference to piezoelectric elements. Flexure vibrations are accordingly generated in X and Y directions. The vibrations in the X direction cause interference with the vibrations in the Y direction and vice versa. An amount of interference, caused by vibrations in one direction, with vibrations in another direction, is correctively eliminated by the control mechanism (interference eliminating unit. A workpiece is thus cut by means of a cutting tool through elliptical vibrations with high precision.

Abstract: Apparatus for making the finishing cut on the internal outline of a rough cut female die has two carriages one sliding in one direction upon the other, and the other carriage sliding upon a base at right angles to the first. A male punch comprising a template of the outline to which the die is to be finish cut is mounted on one carriage and the die or workpiece is mounted in an indexing work holder on the other carriage. The template engages a tracer finger fixed relative to the base and to a hacksaw blade which finish cuts the die or workpiece by strokes with the plane of the blade perpendicular to the die surface being cut. The tracer and blade are in common planes to which one carriage moves perpendicularly and the other parallel. The cutter blade and tracer respectively engage the die or workpiece and punch or template in the same direction so that cutting action urges the template and tracer into engagement.

Abstract: An apparatus trims woodwind instrument reed material for use in bassoons and the like in a precise and efficient manner. A cylindroid section of reed material is attached to the apparatus for rotation about its longitudinal axis. A cam, journalled in parallel relation to the reed material, defines a gradient to be trimmed thereon. The reed material and cam are interlocked for rotation in fixed parallel relation. A reed cutting assembly is pivotally disposed above the reed material and the cam and is movable about the longitudinal axes thereof. The cutting assembly includes a cam follower adjacent the cam and a blade in contacting relation with the reed material. The cutting assembly trims the gradient defined by the cam onto the reed material. The trimming is done by rotating the interlocked reed support and cam assembly about the longitudinal axis of the reed material, while linearly moving the cutting assembly along the longitudinal axis of the reed material.
