Key Findings in This Report

• A novel deep learning retrieval method integrates process design features (modulus, wall thickness, symmetry, length-to-height ratio) with CLIP-based shape features, significantly improving process reuse. • Incorporating process design features boosts retrieval accuracy by 6.09% to 97.82% and increases process similarity by 30.25% on a database of 230 production casting models. • The retrieved process, validated via EasyCast simulation, yields minimal shrinkage in the target model, demonstrating superior process reuse capability. • The method requires no large training dataset, making it highly applicable to casting process design and related manufacturing.
