APPARATUS AND METHODS FOR OPTIMIZATION OF POWDER REMOVAL FEATURES IN ADDITIVELY MANUFACTURED COMPONENTS

Techniques for optimizing powder hole removal are disclosed. In one aspect, an apparatus for inserting powder removal features may identify what powder removal features are optimal for a given AM component, as well as the optimal location and physical characteristics of these features. The features...

Zusammenfassung:	Techniques for optimizing powder hole removal are disclosed. In one aspect, an apparatus for inserting powder removal features may identify what powder removal features are optimal for a given AM component, as well as the optimal location and physical characteristics of these features. The features are automatedly added to the component, and an FEA test is run. In the event of failure, the offending feature is removed and the process is repeated. If successful then the loose powder may be removed in a post-processing step following AM. La présente invention concerne des techniques d'optimisation de l'élimination de trou de poudre. Dans un aspect, un appareil d'insertion des caractéristiques d'élimination de poudre peut identifier que les caractéristiques d'élimination de poudre sont optimales pour un élément AM donné, ainsi que les caractéristiques de localisation et physiques optimales de ces caractéristiques. Les caractéristiques sont automatiquement ajoutées à l'élément, et un test FEA est effectué. En cas de défaillance, la caractéristique d'interruption est retirée et le procédé est répété. En cas de succès la poudre libre peut être retirée dans une étape post-traitement suite à l'AM.
