Nissan Motor Co., Ltd. (Headquarters: Nishi-ku, Yokohama, Kanagawa; President: Makoto Uchida) announced on July 9 that it received the Gold Award in Quality Engineering at the 32nd Quality Engineering Research Presentation Conference, hosted by the Precision Measurement Technology Promotion Foundation, for its research on improving the accuracy of opposed die-less forming.
The opposed die-less forming method involves robots equipped with bar-shaped forming tools that gradually shape panels using incremental forming technology. By placing tools on the opposite side, it enables the formation of complex shapes. This method is suitable for low-volume production of various types, and Nissan currently uses it for manufacturing spare parts for discontinued older models.
This research was highly evaluated for its ability to suppress warping of panels after forming and improve forming accuracy. By utilizing quality engineering experiments, the mechanism of panel warping was elucidated, and various forming conditions, such as tool shape and movement speed, were optimized. This significantly enhanced the dimensional accuracy of the panels after forming.
The award-winning theme is “Setting Conditions for Suppressing Warping to Improve Panel Forming Accuracy in Incremental Forming,” and the awardees are Yoshihiro Kobayashi, Tomoyuki Yoshida, Shinji Nishino, Tatsuo Aiba, Keisuke Nagai, and Kazuyoshi Sata. Nissan also received the Silver Award in 2018 for its efforts to improve casting manufacturing technology.
