| Outline of Final Research Achievements |
Original forming machine for double sides simultaneous forming by friction stir incremental forming with 8 axes (upper and lower forming parts which each set consist of XYZ 3 axes and 1 spindle) was developed. A5052 aluminum alloy sheets were formed by the developed equipment. Convex-concave shape was formed from only single side and double side. Forming accuracy from double side was higher than that from single side. Concave shape was formed from both single side and double side and forming limit and forming accuracy were compared. Forming limit by both methods were same, however, forming accuracy by double side forming was significantly higher than that by single side forming.
