AS ISO ASTM 52921:2020 pdf download.Standard terminology for additive manufacturing一Coordinate systems and test methodologies.
build platform, n—of a machine, any base which provides a surface upon which the build is started and supported throughout the hui Ic! process (see A 1. 1).
DiscussioN—The machine build platform may he solid or perforated and made from a wide variety of materials and constructions.
DiscussioN—In some systems the parts are built attached to the build platform, either directly or through a support structure. In other systems, such as powder bed systems. no direct mechanical fixture between the build and the platform may be required.
build surface, il—area where material is added, normally on the last deposited layer which becomes the foundation upon which the next layer is formed.
DISCUSSION—For the first layer the build surface is often the build platform.
DISCUSSION— lithe orientation of the material deposäion or consolidation means, or both, is variable, it may be defined relative to the build surface (for example. a blown powder head may be kept normal to it. See also Z axis discussion).
front, n—of a machine, shall be designated by the machine builder.
DIscussioN—Generally, this is the side of the machine that the operator faces to access the user interface or primary viewing window, or both. (See A1.1).
machine coordinate system, il—a three-dimensional Cartesian coordinate system as defined by a fixed point on the build platform “with the three principal axes labeled X, Y, and Z, with rotary axes about each of theses axes labeled A, B, and C, respectively” (see Al.!, Al .2, and Al .3) as stated in ISO 841.
origin, n—a designated reference point at which the three primary axes in a Cartesian coordinate system intersect. Synonyms: zero point, or (0, 0, 0) when using X, Y, and Z coordinates.
build t’olu,ne origin, n—shall be located at the center of the build platform fixed on the build facing surface.AS ISO ASTM 52921 pdf download.
