Abstract
Official abstract text for this publication.
A method of optimizing strength in an improved mold for a cast component. The method may include the steps of evaluating a flaw in an existing mold, adding external reinforcement features to a design of the improved mold, manufacturing the improved mold in an additive manufacturing process, and casting the cast component in the improved mold.
First claim
Opening claim text (preview).
We claim: 1. A method of optimizing strength in an improved mold for a cast component, comprising: evaluating a flaw in an existing mold; adding external reinforcement features to a design of the improved mold; manufacturing the improved mold together with the external reinforcement features in an additive manufacturing process; and casting the cast component in the improved mold. 2. The method of claim 1 , wherein the step of adding external reinforcement features to a design of the improved mold comprises adding external ribbing to a section of the improved mold. 3. The method of claim 1 , wherein the cast component is a turbine component, and the step of adding external reinforcement features to a design of the improved mold comprises adding external ribbing to at least one of an airfoil portion and a shank portion of the improved mold. 4. The method of claim 1 , wherein the step of adding external reinforcement features to a design of the improved mold comprises adding gussets to a base portion and/or a shank portion of the improved mold. 5. The method of claim 1 , wherein the cast component is a turbine component, and the step of adding external reinforcement features to a design of the improved mold comprises adding a fillet about an airfoil portion of the improved mold. 6. The method of claim 1 , wherein the step of adding external reinforcement features to a design of the improved mold comprises adding external reinforcement features to a load bearing area of the improved mold. 7. The method of claim 1 , wherein the step of adding external reinforcement features to a design of the improved mold comprises a topological optimization process. 8. The method of claim 7 , wherein the topological optimization process reduces stress concentrations in the improved mold as compared to the existing mold. 9. The method of claim 7 , wherein the step of manufacturing the improved mold in an additive manufacturing process comprises using a ceramic material. 10. The method of claim 9 , wherein the topological optimization process comprises redistributing the ceramic material in the improved mold. 11. The method of claim 10 , wherein the topological optimization process comprises changing a thickness of the ceramic material in the improved mold. 12. The method of claim 1 , further comprising firing the improved mold. 13. The method of claim 1 , wherein the step of adding external reinforcement features to a design of the improved mold comprises a Computer Aided Design process. 14. The method of claim 1 , wherein the improved mold comprises a combined core and shell.
