It has gradually become the only basis for product development, which is a huge change in terms of technology, management and ideas. this The changes make it difficult for the traditional two-dimensional process design standards to be applied to the process design in the three-dimensional environment. In order to effectively solve the three-dimensional work of manufacturing enterprises To solve the bottleneck problem in the application of art design technology, promote the popularization and engineering application of three-dimensional process design technology, and formulate GB/T 41158 "Mechanical Production Product 3D Process Design. According to the working process of three-dimensional process design of mechanical products, it is planned to be composed of seven parts. --- Part 1.Terms and Definitions. The purpose is to standardize the terms and definitions related to the three-dimensional process design of mechanical products, and to unify the related terms and definitions. concepts and avoid communication difficulties, ambiguities and misunderstandings caused by unclear concepts and terminology. --- Part 2.General requirements. The purpose is to classify the three-dimensional process design of mechanical products, the general process and the communication of each key link. Based on the requirements, it focuses on solving the common problems existing in the three-dimensional process of mechanical products, and gives relevant technical requirements. --- Part 3.Model construction. The purpose is to standardize how to build and transfer the process and step models in the three-dimensional process design of mechanical products. It focuses on solving problems such as the process and common requirements of process and step model construction in the process of 3D process design of mechanical products. Avoid rework caused by inconsistent design habits. --- Part 4.Process symbols and markings. The purpose is to standardize machining, sheet metal, welding and assembly in the three-dimensional process design of mechanical products. Match the symbol content, representation and three-dimensional labeling requirements of typical process symbols, and provide basis for the labeling of process symbols in a three-dimensional environment. data and guidance. --- Part 5.Detailed design. The purpose is to standardize machining, sheet metal, welding and The basic process and technical requirements of typical process design such as assembly provide the basis and technical requirements for the detailed design of three-dimensional process design of mechanical products guide. --- Part 6.Data requirements. The purpose is to standardize the data classification, data exchange and sharing requirements in the three-dimensional process design of mechanical products. It focuses on solving the problems of unclear data transfer deliverables and incomplete data at various stages in the 3D process design process of mechanical products. question. --- Part 7.Issue requirements. The purpose is to standardize the distribution content related to the distribution of process results in the three-dimensional process design of mechanical products, The release form and technical requirements provide basis and guidance for the release of process results in a three-dimensional environment. 3D process design of mechanical products Part 3.Model Building1 ScopeThis document specifies the general requirements, basic process, process model change requirements, process model construction in the three-dimensional process design of mechanical products Model checking requirements, as well as detailed modeling processes and requirements for typical process models such as machining, sheet metal, welding, and assembly.

Process model and design model should be related to each other. 4.2 Process model construction generally includes process/step design, process/step geometric model construction, process resource model addition, process information labeling. Note and attribute information definition and other processes. 4.3 In the process of the same product, the front and rear process/step models should be related to each other, and the changes of the previous process/step model should be linked to the subsequent process/step model. Step model. 4.4 The process model can be composed of a set of models corresponding to the creation of each process/step, or it can be composed of a collection of all process features of a centralized process/step. a model composition. 4.5 The process model shall be constructed according to the requirements of the process size and process characteristics and in a 1.1 full-size ratio. 4.6 The process features in the construction of the process model are generally expressed by means of coloring or highlighting. 4.7 Information such as model features and labels of each process/step should be consistent with the content of the process/step, reflecting the technological process of the current process/step. ......Tips & Frequently Asked Questions:Question 1: How long will the true-PDF of GB/T 41158.3-2022_English be delivered?Answer: Upon your order, we will start to translate GB/T 41158.3-2022_English as soon as possible, and keep you informed of the progress.
