  • Publication number: 20230040385
    Abstract: Technology for turning selected portions of a workpiece by a cutting tool is described. The described technology can provide methods and apparatuses for turning areas of a part so that corner strikes are avoided upon material entry, burr formation upon material exit is eliminated or significantly reduced, and/or the instantaneous cut depth continuously changes to avoid notch formation. The resulting superior machining conditions can enable more aggressive machining parameters to be used in the tool path, thereby resulting in reduced machining time and load.

  • Patent number: 10987774
    Abstract: Technology for milling selected portions of a workpiece by a cutting tool of a numerical control machine is described. The described technology provides methods and apparatuses for milling areas of a part so that more aggressive machining parameters can be used in the toolpath, thereby resulting in reduced machining time and load. The described technology additionally determines directions of the tool axis vector at points along a toolpath in order to achieve a desired part shape while optionally maintaining high material removal rates.

  • Patent number: 10579040
    Abstract: Technology for milling selected portions of a workpiece by a cutting tool of a numerical control machine is described. The described technology provides methods and apparatuses for milling areas of a part so that more aggressive machining parameters can be used in the toolpath, thereby resulting in reduced machining time and load. The technology creates a series of toolpath contours where arcs in the toolpath contours are non-concentric with arcs in other toolpath contours. The selected portions of the workpiece are milled by moving the cutting tool in accordance with the toolpath.

  • Patent number: 8880212
    Abstract: Technology for milling selected portions of a workpiece by a cutting tool of a numerical control machine is described. The described technology can receive a main toolpath, the main toolpath comprising one or more cuts; compute one or more transition toolpaths, each transition toolpath defining a transition area intersecting one or more of the cuts of the main toolpath; trim one or more cuts of the main toolpath near two or more points of intersection between the main toolpath and the transition toolpaths; connect the trimmed portions of the main toolpath with one or more connecting moves such that each connecting move is mostly inside one or more of the transition areas; and mill the selected portions of the workpiece by moving the cutting tool in accordance with the cuts, transition toolpaths, trimmed cuts, and connecting moves.
