Patent number: 11724299Abstract: The present disclosure relates to a method for straightening of a tube comprising a ferritic FeCrAl-alloy. One reason for the challenges regarding the cold working of a hollow of a ferritic FeCrAl-alloy into a finished tube is that FeCrAl-alloys have a low ductility. Even if a tube of a FeCrAl-alloy is obtained by cold working a hollow into a tube, the tube can hardly be straightened. This is even more a problem if a tube obtained is annealed, wherein the annealing leads to a deformation of tube along the longitudinal direction of the tube. Therefore, there is a need for a method for straightening of a tube comprising a ferritic FeCrAl-alloy. Thus, according to the present disclosure a method for straightening of a tube is suggested, wherein the method comprises the steps of providing a tube comprising a ferritic FeCrAl-alloy, heating the tube, and straightening and forming the heated tube by stretching.Type: GrantFiled: December 21, 2018Date of Patent: August 15, 2023Assignee: Sandvik Intellectual Property ABInventors: Fernando Rave, Krister Wickman, Thomas Froböse

Patent number: 11720079Abstract: A Web-based system and method creates one or more qualitatively distinct process plans for machining a part. The surfaces of the part are modeled and parameters for a plurality of CNC machining tools are obtained, including the orientations along which the tool cuts away raw material. A maximal set of translations for each tool is also obtained, where each translation includes a collision-free orientation of the tool and a maximal machinable volume of material removable from the part in that orientation. A search engine navigates through a hierarchically-structured search space that starts at an initial state and transitions to successive states based on actions that satisfy a cost constraint function. Each state and each action includes a tool, orientation of the tool, and a maximal machinable volume. The search ends when a goal condition is satisfied. The actions constitute the process plan.Type: GrantFiled: February 14, 2020Date of Patent: August 8, 2023Assignee: SANDVIK INTELLECTUAL PROPERTY ABInventors: Saigopal Nelaturi, Christian Fritz, Gregory Burton, Tolga Kurtoglu
