本文件参照ISO 230-1规定了在垂直轴用于切割操作的普通精度数控（NC）拉床上进行的几何试验。旋转轴的精度（如果可用）参照ISO 230-7进行检查。 本文件还参考ISO 230-2规定了直线轴和旋转轴垂直表面式拉床的定位试验。 本文件参考ISO 230-1《精加工条件下的切削试验》，提出了包含拉刀槽和凹槽的试件。它还规定了试样本身的特性和尺寸。本文件旨在提供评估机器切割精度的最低要求。 本文件还确定了与配备数控的通用和正常精度立式表面拉床相对应的试验结果公差。 本文件解释了通常用于制造涡轮盘的数控立式表面拉床的不同概念或配置以及常见特征。它还参考ISO 841提供了受控轴的术语和名称。 本文件仅涉及拉床精度的验证。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），也不适用于机器特性（例如速度、进给），因为此类检查通常在测试精度之前进行。

This document specifies, with reference to ISO 230-1, the geometric tests on numerically controlled (NC) broaching machines of normal accuracy, with vertical axis acting for cutting operation. The accuracy of rotary axes, if available, is checked with reference to ISO 230-7. This document also specifies, with reference to ISO 230-2, the positioning tests on vertical surface type broaching machines for both linear and rotary axes. This document proposes test pieces containing broached slots and grooves with reference to ISO 230-1, cutting tests under finishing conditions. It also specifies the characteristics and dimensions of the test pieces themselves. This document is intended to supply minimum requirements for assessing the cutting accuracy of the machine. This document also establishes the tolerances for the test results corresponding to general purpose and normal accuracy vertical surface type broaching machines equipped with numerical control. This document explains different concepts or configurations and common features of NC vertical surface type broaching machines which are normally used in the manufacturing of turbine disks. It also provides a terminology and designation of controlled axes with reference to ISO 841. This document deals only with the verification of the accuracy of the broaching 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) as such checks are generally carried out before testing the accuracy.
