1.1 本文件规定了在汽车环境中使用客观测试标准进行通用AM机器评估的方法，并提供了客观AM机器评估和比较的框架。本文件适用于基准测试、采购决策的准备，也适用于机器采购、验收和鉴定过程中的AM机器评估。本文件是针对汽车的，因为它与各种原始设备制造商的现有系列零件要求有关，但如有必要，其内容可以转移到其他行业。 1.2 此外，本文件规定了PBF-LB/M组件的机器采购、生产计划和生产中的机器KPI。 其目的是在机器供应商和机器用户之间就采购过程中的验收标准和运行生产过程中的机器性能评估达成详细的理解。使用本文件时，所有工艺参数，如扫描速度、激光功率等都是固定的，因为更改这些参数会影响整个工艺性能及其稳定性。因此，在鉴定期间或鉴定之后，变量不再发生任何变化。本文档和KPI的确定有助于评估机器特性，但不会取代特定于应用程序的审批流程。 1.3 本文件适用于增材制造技术PBF-LB/M。 1.4 本国际标准是根据世界贸易组织技术性贸易壁垒委员会发布的《关于制定国际标准、指南和建议的原则的决定》中确立的国际公认的标准化原则制定的。

1.1 This document specifies the methodology for generic AM-machine evaluation in automotive environment using objective test criteria and provides the framework for an objective AM-machine evaluation and comparison. This document finds application in benchmarks, in the preparation of purchase decisions, but also in AM-machine evaluation within the machine procurement, acceptance, and qualification processes. This document is specific to automotive, as it is related to existing series part requirements of various original equipment manufacturers, but the content can be transferred to other industries if necessary. 1.2 Furthermore, this document specifies machine KPIs in the context of machine procurement, production planning and production of PBF-LB/M components. It aims to reach a detailed understanding between machine supplier and machine user with respect to the acceptance criteria during the procurement process and evaluation of machine performance during running production. For using this document, all process parameters, such as scanning speed, laser power, etc., are fixed, since changing these parameters can affect the entire process performance and its stability. Therefore, variables are not changed any more during or after qualification. This document and the determination of the KPIs help in the evaluation of machine properties, but do not replace an application-specific approval process. 1.3 This document is applicable to the additive manufacturing technology PBF-LB/M. 1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
