New Methods of Designing Stamping Dies Assemblies by Using Generative Models

摘要

Designing stamping dies assemblies must obey strict rules and requires a lot of technological knowledge and experience. Designed dies exhibit strong similarity and the process, in spite of the complexity and the need to take into account the specifics of pressed shape, is repeatable. Therefore, the design of stamping dies assemblies can be accelerated by applying Generative Modeling method. The paper presents the process of building Generative Model of stamping dies assemblies in the environment of Siemens NX Knowledge Fusion. In addition, the paper presents a method of building a engineering knowledge base for stamping dies assemblies and the user interface for controlling elaborated Generative Model. Knowledge base and its conceptual model is adapted to acquire knowledge from experts by significantly simplifying the structure of the knowledge base and the use of common computer tools. In addition, the results of Generative Model verification and the process of improvement in the performance on the basis of practical design tasks and the introduction of changes resulting from errors that occur during verification are presented. The constructed Generative Model includes knowledge base, software written in Knowledge Fusion and the user interface. The paper also shows the benefits of using Generative Models in designing stamping dies assemblies.
