金沢大学理工研究域機械工学系In the Milling Combined Laser Metal Sintering Process, the overhang shape is formed in the side of the work piece when the following layer is sintered after completing the side of the work piece by milling process. The processing time is long, because the overlapped area to have contained the overhang shape has to be milled. Therefore, making the overhang shape small is required. This paper proposes the laser sintering pattern to reduce the overhang shape, evaluating of how it is formed in the sintering process after the milling process. 金属光造形複合加工法では,ワーク側面の切削仕上げ後,次層のレーザ焼結を行うため,側方と下方に余剰硬化部が形成され,余剰硬化部を含むように切削領域をオーバーラップするので加工時間が増大する。加工時間を短縮するためには余剰硬化部を小さくすることが要求される。本報では,切削仕上工程後の積層焼結工程において,余剰硬化部が層ごとにどのように形成されるかを評価し,余剰硬化部を削減するレーザ照射...
