Pure aluminum sheets were formed into concave-convex shape by friction stir incremental forming using an originally developed penetrating tool. A1050-O sheets with a size of 150 mm x 150mm x 2mm were used for specimens. Concave shape, convex shape and concave-convex shape were formed successfully. Cross-sectional shape of formed sheets was measured by a laser displacement meter. Formed depths for concave, convex and concave-convex shapes were 4 mm, 3 mm and 1.8 mm, respectively.
