To Make A Double Curvature Foil Patents (Class 409/119)
  • Patent number: 11292096
    Abstract: The machine tool has a machine bed having a first horizontal linear guide and a second horizontal linear guide arranged at right angles to the first linear guide. On the first linear guide is arranged, in an axially displaceable manner, a workpiece clamping fixture, which is swivelable about a swivel axis oriented parallel to the second linear guide and is rotatable about a rotation axis oriented at right angles to the swivel axis. On the second linear guide a toque motor driven swivel arm is axially displaceable, the swivel axis of which is arranged parallel to the first linear guide and which on its free end bears a tool spindle, the axis of which is oriented parallel to the first linear guide.

  • Patent number: 9802288
    Abstract: An abrasive profiling tool that may be part of a robotic machining system for machining a trailing edge of an airfoil, includes a shank extending along a rotational axis, a bearing guide rotationally secured to a distal end of the shank for riding upon the airfoil; and an abrasive profiler projecting radially and rigidly outward from the shank for grinding at least the trailing edge as the shank rotates. The profiler may include a round-over portion for grinding the trailing edge and a chamfered blending portion for grinding adjacent surfaces of the airfoil to produce a smooth transition from the adjacent surfaces and to the trailing edge.

  • Patent number: 8389108
    Abstract: A surface-coated cutting tool of the present invention includes a substrate and a coated layer formed on the substrate, and the coated layer is a physical-vapor-deposition layer having a thickness of 10 ?m or more. A surface region having a thickness of 1 ?m from a surface of the coated layer includes a first region whose integrated residual stress is a compressive stress and a second region whose integrated residual stress is a tensile stress, and the integrated residual stress of the surface region falls within the range of ?1.5 to 1.5 GPa in any region included in the surface region.

  • Patent number: 4856947
    Abstract: Milling and cutting of curved mold surfaces is controlled by templates, each defining a cam surface to be scanned; one of the templates is pivoted by lateral shift operation of a second template, there being a linkage interposed.
