标准范围

本文件规定了定义制造精确试样的加工试验的方法，以及评估线性轴和旋转轴的准静态几何误差的影响，以及同时控制的多个轴的同步误差的影响的方法。虽然准静态几何误差通常是成品试件几何误差的主要因素，但其他因素，例如动态轮廓误差，也可能有重大影响。本文件描述了适用于单个机床的试件几何形状示例、加工误差的可能原因、待测量的偏差和测量仪器。通过澄清每次加工试验中可能导致加工误差的因素，本文件为机床制造商或用户提供了指导，以便选择适当的加工试验来评估特定加工应用中机床的加工性能。用于评估单个表面几何精度的加工试验在第条中进行了描述第5条中描述了评估多个加工特征的几何关系的方法6.条款7介绍了其他目标的加工试验:用于评估短期能力的加工试验（7.2），以及用于评估热影响的加工试验（7）。3).

This document specifies methods for defining machining tests for manufacturing accurate test pieces, and for evaluating the influence of quasi-static geometric errors of linear axes and rotary axes, and the influence of the synchronization error of simultaneously controlled multiple axes. Although quasi-static geometric errors are often major contributors for geometric errors of finished test pieces, other factors, e.g. the dynamic contouring error, can also have significant influence.This document describes examples of test piece geometry applicable to individual machine tools, possible contributors to machining error, deviations to be measured and measuring instruments. By clarifying possible contributors to machining error in each machining test, this document gives a guidance to machine tool manufacturers or users such that proper machining tests can be chosen to evaluate a machine tool’s machining performance in specified machining applications.Machining tests to evaluate the geometric accuracy of a single surface are described in Clause 5, and those to evaluate geometric relationship of multiple machining features are described in Clause 6. Clause 7 presents machining tests for other objectives: machining tests for evaluation of short-term capability (7.2), and machining tests for evaluation of thermal influence (7.3).
