加工中心检验条件.第1部分:带水平主轴的机床的几何精度检验(水平Z轴)

[中文适用范围]： ISO 10791 的这一部分，参照 ISO 230-1，规定了带有水平主轴（即水平 Z 轴）的机床（或适用的其他数控机床）的几何试验。 ISO 10791 的这一部分适用于具有三个数控直线轴（X 轴长度可达 5 000 毫米，Y 轴长度可达 3 200 毫米，Z 轴长度可达 2 000 毫米）的机床，但也参考补充运动，如旋转、倾斜和摆动表台的运动。除上述提及的运动外，其他运动被视为特殊功能，ISO 10791 的这一部分不包括相关试验。 ISO 10791 的这一部分在附录 A 至 D 中考虑了四种可能的表台类型，固定和旋转，描述如下： —— 附录 A：水平非旋转表台； —— 附录 B：绕垂直 B'-轴旋转的表台； —— 附录 C：绕垂直 B'-轴旋转并绕水平 A'-轴倾斜的表台； —— 附录 D：绕水平 A'-轴旋转并绕垂直 B'-轴摆动的表台。 ISO 10791 的这一部分不考虑附件主轴，由 ISO 17543-1 涵盖。 ISO 10791 的这一部分仅处理机床几何精度的验证，不适用于机床操作的测试，机床操作测试通常应单独检查。不涉及机床纯几何精度的试验在 ISO 10791 的其他部分中处理，如前言所列。 [外文原描述]： ISO 10791-1:2015 specifies, with reference to ISO 230 1, the geometric tests for machining centres (or other numerically controlled machines, where applicable) with horizontal spindle (i.e. horizontal Z-axis). It applies to machining centres having three numerically controlled linear axes (X-axis up to 5 000 mm length, Y-axis up to 3 200 mm length, and Z-axis up to 2 000 mm length), but refers also to supplementary movements, such as those of rotary, tilting, and swivelling tables. Movements other than those mentioned are considered as special features and the relevant tests are not included. It takes into consideration four possible types of tables, fixed and rotary: horizontal non-rotating tables; tables rotating around a vertical B'-axis; tables rotating around a vertical B'-axis and tilting around a horizontal A'-axis; tables rotating around a horizontal A'-axis and swivelling around a vertical B'-axis. It does not consider accessory spindle heads, which are covered by ISO 17543-1. ISO 10791-1:2015 deals only with the verification of geometric accuracy of the machine and does not apply to the testing of the machine operation, which should generally be checked separately. Tests not concerning the pure geometric accuracy of the machine are dealt with in other parts of ISO 10791.
