ISO 10791的本部分参考ISO 230-1规定了加工中心（或 数控铣床、镗床等（如适用），带有整体可转位或 连续通用磁头（垂直Z轴）。 ISO 10791的本部分适用于基本上有六个数控轴的加工中心，其中三个轴 是线性的（X、Y和Z），长度可达2000毫米，三个是旋转的（头部是A或D和B，头部是C’） 表）。除上述运动外，其他运动被视为特殊特征，相关测试不适用 包括在ISO 10791的本部分中。 ISO 10791的这一部分描述了三种可能类型的附件万向头的几何试验 附件: -附录A:整体式通用45°分体式可转位头（B轴和D轴），具有不同 两个机构（例如Hirth联轴器）的角度位置:相关测试（AG1至AG9）仅检查 主轴的最终位置； -附件B:带两个数控旋转轴的整体式通用旋转头（B轴和A轴） 相互垂直（测试BG1至BG7）； -附录C:整体式通用45°分体式连续封头（B轴和D轴），类似于第一种类型，但配有 两个数控旋转轴的连续定位:相关测试（CG1至CG7）检查所有 构成主轴最终位置的几何特征（平面和轴），不包括 两个旋转轴的定位精度；这些测试也可用于对45°的深度调查 可转位的头部，如果它们的运动和锁允许的话。 ISO 10791的本部分仅涉及机器精度的验证，不适用于测试 机器运行情况，通常应单独检查。有关性能的某些测试 ISO 10791的其他部分包括了在空载或精加工条件下运行的机器。

This part of ISO 10791 specifies, with reference to ISO 230-1, the geometric tests for machining centres (or numerically controlled milling machines, boring machines, etc., where applicable) with integral indexable or continuous universal heads (vertical Z-axis). This part of ISO 10791 applies to machining centres having basically six numerically controlled axes, of which three are linear (X, Y and Z) up to 2 000 mm in length, and three are rotary (A or D and B on the head, and C' on the table). Movements other than those mentioned are considered as special features and the relevant tests are not included in this part of ISO 10791. This part of ISO 10791 describes geometric tests for three possible types of accessory universal heads, in the annexes: — annex A: Integral universal 45° split indexable heads (B and D axes), with mechanical indexing of the different angular positions of the two bodies (e.g. Hirth couplings): the relevant tests (AG1 to AG9) check only the resulting position of the spindle; — annex B: Integral universal swivel heads (B and A axes), with two numerically controlled rotary axes perpendicular to each other (tests BG1 to BG7); — annex C: Integral universal 45° split continuous heads (B and D axes), similar to the first type but provided with continuous positioning of the two numerically controlled rotary axes: the relevant tests (CG1 to CG7) check all the geometric features (planes and axes) which contribute to the resulting position of the spindle, excluding the positioning accuracy of the two rotary axes; these tests can also be used for a deeper investigation on the 45° indexable heads, if their movements and locks allow this. This part of ISO 10791 deals only with the verification of accuracy of the machine and does not apply to the testing of the machine operation, which should generally be checked separately. Certain tests concerning the performance of the machine operating under no-load or finishing conditions are included in other parts of ISO 10791.
