This document is intended for additive manufacturing service platforms, defining datasets for data information in the design, process, materials, and equipment stages to facilitate various aspects. The filtering, integration, fusion, sharing, and analysis of dataset information aim to achieve interoperability between additive manufacturing application services and their datasets, ensuring... The definition, interaction, and integration of information from the "design end" to the "manufacturing end" are accurate, complete, and effective. Additive manufacturing service platforms include existing software, online platforms, and other platforms that provide additive manufacturing services, as well as future platforms. A new form of additive manufacturing service platform has been developed. Additive Manufacturing Dataset Definition and Interaction

1.Scope This document specifies the basic requirements for defining and interacting with additive manufacturing datasets, the connotation and requirements of datasets, and the rules for interaction between datasets. Interaction. This document applies to the design dataset, process dataset, material dataset, and equipment information dataset of the additive manufacturing service platform. Interaction.

4 Basic Requirements

4.1 Basic Requirements for Dataset Definition An additive manufacturing dataset consists of a name, identifier, constraints/conditions, data type, and data field, and must meet the following requirements.

a) The dataset name should not be empty;

b) Dataset names should use the character set specified in GB/T 1988 and should not contain special characters;

c) Dataset identifiers should begin with a specific symbol (such as "`" or "@") or an underscore "_", followed by letters, numbers, etc. A line or a specific symbol;

d) The length of the dataset identifier should be less than the maximum length specified by the computer system of the service platform used;

e) Data sets should define data types, such as integers, floating-point numbers, booleans, strings, and dates;

f) The data field should specify a range of values. See Appendix A for a format example of the additive manufacturing dataset.

4.2 Basic Requirements for Dataset Interaction The additive manufacturing service platform uses design data, process data, material data, and equipment data to form design datasets, respectively. Process datasets, material datasets, and equipment information datasets are stored in a specific database. Through the interaction of these datasets, design and process... Interoperability between processes such as technology and manufacturing. Additive manufacturing dataset interaction must meet the following requirements.

a) The dataset should maintain data consistency with the corresponding system;

b) The integrity of the data information should be maintained when performing necessary format conversions on the dataset;

c) Data set interaction should implement data access control to ensure data security;

d) Data interfaces should be established between datasets to ensure data interaction between systems such as design, process, and manufacturing.

6 Dataset Interaction

6.1 Interaction Method Figure 1 illustrates the interaction between datasets. In Figure 1, the outer arrows indicate data relationships between datasets; the inner arrows... The arrows indicate how data from different datasets interact within the application service through methods such as calling, merging, and modifying. The datasets are used in the additive manufacturing process. An application example is shown in Figure B.1 in Appendix B.

6.2 Interaction Flow Additive manufacturing achieves the transformation from design to physical manufacturing through key steps including model design, process data processing, and process implementation. (Data...) The data sets interact with each other through application services (various software and network platforms that provide additive manufacturing services), thereby enabling data exchange. Functions such as querying, calling, modifying, and merging enable interconnection and interoperability among the design, process, and manufacturing stages in the additive manufacturing process. An example of the correlation between data in the dataset is shown in Figure B.2. Examples of the main functional modules of the application service, such as database management and query proxy, are shown in Appendix C.
