NF EN ISO/ASTM 52945, E67-020 (01/2024)

This document specifies the methodology for generic evaluation of AM machine in the automotive sector using objective test criteria and provides the framework for objective evaluation and comparison of AM machine. This document finds its application in benchmarks, in the preparation of purchasing decisions, but also in the evaluation of the AM machine as part of the acquisition, acceptance and qualification processes of the machine. This document is specific to automotive, as it relates to existing serial part requirements from various original equipment manufacturers, but the content can be transferred to other industries if necessary. Furthermore, this document specifies machine KPIs in the context of machine acquisition, production planning and production of PBF-LB/M components. It aims to achieve a detailed understanding between the machine supplier and the machine user regarding the acceptance criteria during the procurement process and the evaluation of machine performance during production. For the use of this document, all process parameters, such as scanning speed, laser power, etc., are fixed, because changing these parameters may affect the overall process performance and stability . Therefore, variables are no longer changed during or after qualification. This document and the determination of KPIs assist in evaluating machine properties, but do not replace an application-specific approval process. This document is applicable to PBF-LB/M additive manufacturing technology.
