Publication number: 20230040385Abstract: 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.Type: ApplicationFiled: June 14, 2022Publication date: February 9, 2023Inventors: Glenn Coleman, Joseph McChesney, Evan C. Sherbrooke

Patent number: 10987774Abstract: 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.Type: GrantFiled: July 2, 2018Date of Patent: April 27, 2021Assignee: Celeritive Technologies, Inc.Inventors: Evan C. Sherbrooke, Glenn Coleman

Patent number: 10579040Abstract: 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.Type: GrantFiled: October 19, 2018Date of Patent: March 3, 2020Assignee: Celeritive Technologies, Inc.Inventors: Evan C.
