AI Technical Summary
Existing automatic annotation technologies in 3D mold assembly design cannot fully extract feature boundaries when facing complex curved surfaces. The establishment of the reference coordinate system relies on manual definition and lacks an automatic judgment mechanism, resulting in deviations in the identification of key geometric elements. The annotation system lacks full parametric driving capability, and the annotation cannot be automatically updated after design changes, causing data disconnect and making it impossible to directly reuse it in downstream systems.
By using a geometric structure intelligent recognition algorithm based on curvature features, the system automatically extracts mold feature points and curves, establishes a reference coordinate system for multi-region fitting and iterative optimization, constructs a tolerance transfer chain to optimize assembly constraint parameters, introduces dimension sensitivity analysis and conflict resolution mechanisms, and realizes bidirectional association and synchronous updating of annotation information and 3D model.
It significantly improves the accuracy and completeness of mold feature extraction, ensures high confidence of coordinate system data, enhances the robustness of design data and the clarity of annotation results, realizes synchronous updates of annotation information and model, opens up the data flow from design to manufacturing, and improves the quality and integration level of 3D mold design.
