本文件参照ISO 230-1和ISO 230-7规定了通用普通精度数控（NC）车床和带有垂直工件夹持主轴的车削中心的几何试验，以及相应的适用公差。 本文件解释了数控车削机和带有垂直工件夹持主轴的车削中心的不同概念或配置以及常见特征。它还提供了受控轴的术语和名称（见图1、图2和表1）。 本文件仅涉及机器精度的验证。它不适用于机器的运行测试（例如振动、异常噪音、部件的粘滑运动）或机器特性（例如:。 g、 速度，饲料）。与机器几何精度无关的试验在ISO 13041的其他部分中进行了说明。

This document specifies, with reference to ISO 230？1 and ISO 230？7, the geometric tests for general-purpose normal accuracy numerically controlled (NC) turning machines and turning centres with vertical workholding spindles, as well as the corresponding applicable tolerances. This document explains different concepts or configurations and common features of NC turning machines and turning centres with vertical workholding spindles. It also provides a terminology and designation of controlled axes (see Figures 1, 2 and Table 1). This document deals only with the verification of the accuracy of the machine. It does not apply to the operational testing of the machine (e.g. vibration, abnormal noise, stick slip motion of components) nor to machine characteristics (e.g. speeds, feeds). Tests not concerning the geometric accuracy of the machine are dealt with in other parts of ISO 13041.
