This study investigates the thickness variation behavior of deep drawing conical products under effect different forming parameters such as die wall inclination angle, punch velocity, sheet thickness, and metal type. Two types were used, low carbon (AISI 1008) galvanized steel sheets, 110 mm diameters circular blanks at 0.9 1.2mm formed by tooling set (punch, die, blank holder). The dies angles...

Friction stir welding (FSW) is a solid-state jointing technology, and has the advantages of high joint strength, low residual stress, small deformation after welding. During FSW, temperature directly influences quality weldment. A heat generation model FSW medium thickness aluminum alloy 2219 established considering friction generated at interface between tool workpiece plastic weldment materia...
