| Abstract Scope |
A new forming method for PMMA sheets using friction stir incremental forming was proposed. In this method, A5052 sheets, A1050 sheets and PMMA sheets are overlapped and formed simultaneously. PMMA sheets which size was 185 mm x 185 mm and thickness were 0.5, 0.2 and 2 mm were employed for specimens. A hemispherical tool with a diameter of 6 mm was used. The tool was rotated at 6000 - 12000 rpm and moved at 1000 - 4000 mm/min. Sheets were formed into a frustum of conical shape with the height of 40 mm and wall angles of 45° - 65°. Shape of formed sample was measured and compared with the objective shape. From the experimental results, formed sheet surface roughness was Ra = 4.45 μm and Rz = 25.89 μm. The limit of formable wall angle was 60°. |
