AS ISO/ASTM 52921:2020 pdf free.Standard terminology for additive manufacturing – Coordinate systems and test methodologies.
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 he compliant with ISO 841 and to clarify the specific adaptation of those principles to addilive man u factu ring.
Nom I—The applicability of this standard to cladding has to be evaluated. Discussions are under progress.
Nom 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 uny associated with its use. Ii is the responsibility of the user of this standard to establish appm— p ri at e safety and health practices and deternune the applica— hi!itv of regulatory limitations prior to use.
3. 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 suflicient 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 complcmcnt 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.AS ISO/ASTM 52921:2020 pdf free.
