Abstract
Description
図2を参照すると、例示的な実施形態では、鋳造モジュール12は、スクラップ収集容器24、XRF分析機器26、鋸28、混合コールドハース30、ガス噴霧システム32、サイクロン34、およびSEM分析装置36を含む。
再び図1を参照すると、付加製造モジュール14は、合金粉末48およびレーザーまたは電磁エネルギーのいずれかを使用して付加製造プロセスを実行するように構成された3Dプリンター50を含む。3Dプリンター50では、合金粉末48が溶融され、構築基板上に層ごとに堆積され、粒子を固め、部品を形成する。パーツが形成されたら、帯鋸またはEDM(放電加工)で切断して構築プレートから取り外する。1つの適切な3Dプリンター50は、EOS GmbHエレクトロオプティカルシステムズによって製造されたEOS M100 3Dプリンターである。
再び図1を参照すると、機械加工モジュール16は、余分な材料を除去し、表面粗さを修正するように構成された機械加工システム54を含む。3D印刷後、印刷されたままの部品の表面は粗く、わずかな寸法の不正確さがある。これらの問題を解決するには、パーツの印刷が少し厚すぎる。余分な材料は後で機械加工中に除去され、パーツは指定された寸法になる。また、熱処理中に部品の表面にスケールが形成される場合がある。このスケールは、ショットブラストで除去して、後処理での機械加工の問題を防ぐことができる。ショットブラスト後、印刷された部品を寸法仕様に機械加工することができる。旋削センターを使用して、余分な材料を取り除くことができる。表面仕上げの要件によっては、研磨も必要になる場合がある。一部の部品では、成形技術を実行して部品の寸法を変更できる。さらに、耐食性を提供するために、1つまたは複数の保護コーティングを各部品に適用することができる。
再び図1を参照すると、品質適合(QC)モジュールは、金属部品を検査および評価するように構成された検査および評価システム56を含む。部品の測定値が許容範囲内にあることを確認することにより、部品がその設計の仕様を満たしていることを確認する。たとえば、製造されたすべての部品に対して仕上がり検査を実行できる。X線CTまたは別の方法を使用して、重要な材料の内部構造に欠陥や亀裂がないか視覚的に検査することもできる。仕上がり検査には、欠陥がないことを確認するために各部品の目視検査が含まれる。欠陥のある部品は、故障分析のためにロットから削除される。三次元測定機(CMM)または別の方法を使用して、部品の寸法を確認することもできる。さらに、材料の硬さを測定し、引張試験を行うことができる。部品に保護コーティングが施されている場合は、コーティングの厚さを測定し、耐食性を塩水噴霧または別の方法でテストできる。
図3を参照して、金属部品を製造するための例示的なプロセスが示されている。図3では、楕円形は材料と部品を示し、長方形はプロセスと機器を表している。矢印は、材料または部品がさらに処理するために1つのモジュールから別のモジュールに取り出されていることを示している。最初に、展開可能な製造センター(DMC)システム10は、遠隔地または戦場などの所望の場所に搬送される。
