1.1 该术语包括术语、术语定义、术语描述、术语和首字母缩略词，这些术语与坐标系和附加制造（AM）技术的测试方法有关，旨在标准化AM用户、生产者、研究人员、教育工作者、媒体和其他人使用的术语，尤其是在报告AM系统上制造的零件测试结果时。术语包括机器/系统及其坐标系的定义，以及零件的位置和方向。 在可能的情况下，其目的是符合ISO 841，并阐明这些原则对添加剂制造的具体适应性。 注1: 必须评估本标准对包层的适用性。讨论正在进行中。 注2: 本标准不包括非笛卡尔系统。 1.2 本标准并非旨在解决与其使用相关的所有安全问题（如有）。本标准的用户有责任在使用前制定适当的安全、健康和环境实践，并确定监管限制的适用性。 1.3 本国际标准是根据世界贸易组织技术性贸易壁垒（TBT）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》中确立的国际公认标准化原则制定的。 ====意义和用途====== 3.1 尽管许多附加制造系统在很大程度上基于计算机数控（CNC）原理，但CNC特有的坐标系和术语不足以适用于所有附加制造设备。 该术语扩展了ISO 841的原则，并将其专门应用于增材制造。虽然本术语旨在补充ISO 841，但如果出现任何冲突，本术语应优先用于添加剂制造应用。对于本术语中未涵盖的任何问题，可采用ISO 841中的原则。 3.2 此外，本术语未规定AM从业者可能希望用于测试目的的任何特定现有测试方法或标准的使用； 然而，预计从业者将采用适当的现有方法和标准来测试AM制造的零件。

1.1 This terminology includes terms, definitions of terms, descriptions of terms, nomenclature, and acronyms associated with coordinate systems and testing methodologies for additive manufacturing (AM) technologies in an effort to standardize terminology used by AM users, producers, researchers, educators, press/media, and others, particularly when reporting results from testing of parts made on AM systems. Terms included cover definitions for machines/systems and their coordinate systems plus the location and orientation of parts. It is intended, where possible, to be compliant with ISO 841 and to clarify the specific adaptation of those principles to additive manufacturing. Note 1: The applicability of this standard to cladding has to be evaluated. Discussions are under progress. Note 2: Non-cartesian systems are not covered by this standard. 1.2 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. 1.3 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. ====== Significance And Use ====== 3.1 Although many additive manufacturing systems are based heavily upon the principles of Computer Numerical Control (CNC), the coordinate systems and nomenclature specific to CNC are not sufficient to be applicable across the full spectrum of additive manufacturing equipment. This terminology expands upon the principles of ISO 841 and applies them specifically to additive manufacturing. Although this terminology is intended to complement ISO 841, if there should arise any conflict, this terminology shall have priority for additive manufacturing applications. For any issues not covered in this terminology, the principles in ISO 841 may be applied. 3.2 Furthermore, this terminology does not prescribe the use of any specific existing testing methodologies or standards that practitioners of AM may wish to employ for testing purposes; however, it is expected that practitioners will employ appropriate existing methodologies and standards to test parts made by AM.
