Features 01
Expected Problems
Don't you have these kinds of problems in outer shape evaluation of press-formed parts?
? Variations occur in evaluation results due to errors by measuring personnel and the ambiguity of standards.
? Accurate comparison is not possible because of the difficulty of superimposing shapes due to springback and deformation.
? Improvement measures cannot be developed because it is not possible to identify the cause of differences in the shape in the analysis model and the actual formed part.
? Improvement of dimensional accuracy is time-consuming because adjustment of the forming conditions is a manual search process.
Features 02
Technology highlight
? Preparation of a highly accurate outer shape model utilizing measured 3D shape data after springback of formed parts (Fig. 1).
? Detailed comparison of the outer shape prediction results by elastoplastic FEM analysis and measurement-based forming model (Fig. 2).
? Improvement of the predictive accuracy of the analysis model by quantitative evaluation of shape differences.
? Improvement of dimensional accuracy by optimization of press-forming conditions based on analysis results.
? Achievement of high reproducibility and accuracy, contributing to high efficiency in evaluation work and stabilization of manufacturing quality.
