  • METHOD AND SYSTEM FOR FEATURE SOFTENING OF A WORKPIECE
    Publication number: 20240238903
    Abstract: Methods and systems are provided for softening a feature of a workpiece. A method for feature softening includes generating a nominal path for softening the feature. Defining points of the workpiece are selected for accuracy of the softening. The workpiece is formed, fixtured in a workstation and imaged. From the imaging and by a processor, an actual location of the defining points on the workpiece as formed and fixtured in the workstation is determined. The processor determines an error between the actual location of the defining points and the design location of the defining points; generates a revised path for softening the feature of the workpiece; guided a material movement machine along the revised path; and softens, by the material movement machine, the feature of the workpiece.
