Control Effects of Thermal Deformation by Machine Tool using Environmental Characteristics of the Factory Naohiko Suzuki・Shouta Shinmoto・Yusuke Nanbu・Yoshiaki Ishino (Takamatsu Machinery) Thermal displacement affects the machining accuracy of machine tools, and various countermeasures are being considered. For example, there are methods to suppress the temperature rise of the machine by cooling the heat source. The most common method for cooling heat sources is to circulate cooling water at a constant temperature, but this involves an increase in cost and energy consumption. This study devised a way to stabilize machining accuracy by utilizing the environmental characteristics of a factory and devising a machine tool bed structure that utilizes air with a relatively stable ambient temperature. |

Development of Element Technologies for Integrated Hot-Stamping Parts Naoki Kimoto・Masahiro Kubo・Kenta Ikegami・Toru Yonebayashi・Tasuku Zeniya・Satoshi Shirakami・Hiroshi Yoshida (Nippon Steel) The author's group has been developed element technologies for integrated hot-stamping parts. In this study, a structure has been developed that produces high crashworthiness using high-strength materials. And a formability improvement method has been developed that controlled the flow of steel sheet at the corners where it is difficult to form in integrated parts. |

Strength Improvement of CFRTP by Mixing Long and Short Fibers Mutsuki Hamada・Taichi Umedu・Souichiro Nishino (Ibaraki University)・Hidemaru Sootome (Industrial Technology Innovation Center of Ibaraki Prefecture) CFRTP, with its light weight and high rigidity, is finding increasing application as a structural material. On the other hand, there is a problem that carbon fibers damage molds during injection molding. In this study, a method was devised to maintain strength even when the amount of carbon fibers is reduced by mixing long and short fibers. We report on the results of CT scans and fracture surface observations of the mixture of long and short carbon fibers. |
