  • Patent number: 7918630
    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.

  • Patent number: 6507984
    Abstract: A detailing tool for processing electronic component substrate includes a supporting frame, a substrate carrier movable on the supporting frame to receive and secure the substrate during processing by the tool, and a pair of cutter assembly attached to said supporting frame for removing tails on said substrate. The cutter assemblies self-align “to” the substrate during initial substrate loading in a processing area of the tool. Each cutter assembly includes a pair of spaced, translatable and opposed cutters that simultaneously move towards each another while removing the tails from the corners of the substrate that remains stationary. The pair of cutter assemblies are symmetrically attached to the supporting frame with respect to an axis for indexing the substrate. Thus, the invention provides a tool for cutting tails from opposite corners on the substrate edge automatically and simultaneously during processing.

  • Patent number: 4693649
    Abstract: An apparatus and method for imparting a sharp, defect-free outside corner of a desired angle to a metal workpiece are disclosed. The apparatus comprises two separate cutting tools, each with a distinct cutting direction. The tools are juxtaposed such that their leading surfaces are adjacent to each other and that their respective cutting edges intersect at the desired angle. This provides that the cutting directions of each tool are opposite one another. In using the improved cutting apparatus, the workpiece is secured and the apparatus must be movable along the x, y and z axes. By cutting the first and second surfaces of the workpiece in sequence with the first and second cutting edges of the present apparatus respectively, a sharp defect-free corner of the desired angle can be imparted to the workpiece. A specific application for the present invention is in the fabrication of intricate copper products, such as heatsinks for semiconductor devices.
