METAL ADDITIVE MANUFACTURING METHOD AND APPARATUS THEREOF

To provide a metal additive manufacturing method due to additive manufacturing capable of performing an adjustment process in series with the additive process with good controllability and accuracy.SOLUTION: The present invention relates to a metal additive manufacturing apparatus and method for modeling a metal additive manufacturing object by supplying a metal material onto a modeling stage and moving a localized melted part by an irradiated heat source. The device includes a movement control unit that positions a tip of a pressing tool at the rear in a moving direction of the local melting part, and freely maintains and controls a separation distance of the tip from the modeling stage, and it is characterized in that it slides following the movement of the local melting part while pressing the tip against the metal material. The method involves sliding the tip following the movement of the local melting part while pressing the tip against the metal material, in the movement control unit that positions the tip of the pressing tool at the rear in the moving direction of the local melting part, and freely maintains and controls the separation distance of the tip from the modeling stage.SELECTED DRAWING: Figure 1 【課題】付加工程と一連とした調整工程を制御性良く精確に実施し得る付加製造による金属積層造形方法及びその装置の提供。【解決手段】造形ステージ上に金属材料を供給し照射される熱源による局所溶融部を移動させて金属積層造形物を造形する金属積層造形装置及び方法である。装置は、押圧工具の先端部を局所溶融部の移動方向の後方に配置させ、造形ステージに対する先端部の離隔距離を自在に保持して制御する移動制御部を含み、先端部を金属材料に押圧させつつ局所溶融部の移動に追従して摺動させることを特徴とする。方法は、押圧工具の先端部を局所溶融部の移動方向の後方に配置させ、造形ステージに対する先端部の離隔距離を自在に保持して制御する移動制御部にて、先端部を金属材料に押圧させつつ局所溶融部の移動に追従して摺動させることを特徴とする。【選択図】 図１
