Background/Objectives: To reduce the production cost by implementing Design for casting instead of machining a component. Methods/Statistical Analysis: A machined component is analysed for its strength to failure. Using casting allowable, the same component is re-analysed and verified for feasibility. The design is compromised without making changes at the interfaces so that the installation is simple. Finally the weight is compared to conclude the application of appropriate production method for cost effectiveness. CATIA V5R21 software is used for designing and PATRAN/NASTRAN is used to analyse the components. Findings: Based on the analysis results critical portions are identified and further changes have been made based on casting design without disturbing the critical portions of the components. The redesigned casting model is analysed to monitor further changes and to find effective method of manufacturing. Application/ Improvement: In this paper, analyses have been made for conventional model and casting design model using PATRAN/ NASTRAN software. Further research will show the effective method to manufacture Aero Engine components.
