Abstract
The present invention relates generally to deformation machining systems and methods that combine, in a single machine tool setup, the machining of thin structures and single point incremental forming (SPIF), such that novel part geometries and enhanced material properties may be obtained that are not achievable using conventional machining or forming systems and methods, individually or collectively. Important to many applications, lighter weight parts may be produced at lower cost using a conventional 3-axis computer numerically controlled (CNC) machine tool or the like, instead of the conventional 5-axis CNC machine tool or the like that is typically required.
