A generalised CAD/CAM solution to the three-dimensional off-centric extrusion of shaped sections: Analysis
The authors employ the upper-bound theory to analyse the three-dimensional off-centric extrusion of shaped sections using the streamlined dies. A set of generalized kinematically admissible velocity fields are derived on the assumption of Bezier-type streamlines, that provides compatibility of surface representation with most CAD/CAM solutions.
