“…Wang et al [30] analyzed and studied the modularization of trimming die from the perspective of assembly based on the relationship between structure and function of trimming die for automobile covering parts and developed a CAD system of trimming die based on UG NX software. For the complex non-standard trimming mechanism, a parametric modeling method [31] and a design method based on feature reuse [32] are proposed to reduce the design difficulty from two dimensions of design and reuse. Mold design is a complex process that requires significant expertise.…”

The stamping process analysis and layout of automotive panels are extremely complex and time-consuming, which directly affects the quality and cycle of product development. Based on the CAGD theory of complex curves and surfaces, process design knowledge, and multidisciplinary optimization techniques, an intelligent automatic process analysis and layout system has been developed. The process feature analysis method based on discretization and merging idea has been proposed to accurately and automatically identify process features such as piercing, trimming, flanging and restricting. The process feature dispersion method based on curvature and normal variation of the forming surface is proposed to ensure the accuracy of feature dispersion. The combinatorial optimization algorithm is proposed to merge the discrete features according to the stamping direction and the geometric parameters of the features to reduce the number of process steps as much as possible. Moreover, a process constraint diagram with combined features is constructed, which is used as the initial solution and sequence constraint conditions for the process layout to effectively ensure the rationality of the process layout. Based on the die design rules, the simplified tools of the process features are created, and the rapid interference detection algorithm of the tools is proposed to realize the automatic layout and optimization of the stamping process. Finally, the aforementioned algorithms are seamlessly integrated into the NX software to develop an automatic analysis and layout system for the automotive panel stamping process. The feasibility, accuracy and efficiency of the system have been demonstrated through the example of the wing panel and the system has been successfully applied in enterprises.

A product is composed of several components, and the number, type, and combination of components plays a crucial role in the process of product design. It is difficult to get an optimized scheme in a short time. In order to improve the efficiency of product design, a product design scheme recommendation algorithm based on multi-way tree and learning-to-rank is proposed. Firstly, the product solution model, whose nodes are obtained by mapping the product attributes, is generated according to the design process, and the alternative scheme is obtained by traversing the multi-tree model. Secondly, considering users’ cognition of the importance of each product attribute, the analytic hierarchy process (AHP) is applied to assign weight to the product attribute, and then similarity to ideal solution (TOPSIS) method based on AHP is used to rank alternative solutions. Furthermore, according to users’ preference for parts’ supplier information, the learning-to-rank algorithm is used to optimize the list of alternative schemes twice. Finally, taking the design of the hoist as an example, it was verified that the proposed method had higher efficiency and better recommendation effect than the traditional parametric design method.
