标准范围

本文件通过参考ISO 230的相关部分，规定了具有水平或垂直主轴或具有不同类型、独立或集成在柔性制造系统中的通用头的加工中心的多个试验系列。本文件还确定了与通用和正常精度加工中心相对应的试验结果的公差或最大可接受值。当数控铣床和镗床的配置、部件和运动与本文所述的试验兼容时，本文件也完全或部分适用于数控铣床和镗床。本文件参考ISO 230-1《精加工条件下的切削试验》规定了标准试样。它还规定了试样本身的特性和尺寸。本文件旨在提供评估具有3到5个同时加工轴的加工中心的切割精度的最低要求。附录A介绍了五轴加工中心的自由形式试件。该加工试验适用于使用自由曲面五轴侧铣的加工中心。

This document specifies, by reference to the relevant parts of ISO 230, several families of tests for machining centres with horizontal or vertical spindle or with universal heads of different types, standing alone, or integrated in flexible manufacturing systems. This document also establishes the tolerances or maximum acceptable values for the test results corresponding to general purpose and normal accuracy machining centres.This document is also applicable, totally or partially, to numerically controlled milling and boring machines, when their configuration, components, and movements are compatible with the tests described herein.This document specifies standard test pieces 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 machining centres with 3 to 5 simultaneous machining axes. Annex A introduces a freeform test piece for five-axis machining centres. This machining test is applied to machining centres using five-axis flank milling of freeform surfaces.
