Abstract

The cross-sectional method is undoubtedly the most widely used method of measuring cylindricity. The method consists of measurements of roundness profiles in several cross-sections of the cylindrical surface. Usually, the distance between subsequent cross-sections is equal. The number of cross-sections used depends on the required accuracy of the assessment of the cylindricity deviation. If one wants to get only rough estimation of the cylindricity deviation, then the measurement can be made in a few cross-sections only. However, if the required measurement accuracy is high, measurements should be carried out in a large number of cross-sections. The consequence of taking the measurements in a large number of sections is significant extension of the measurement time. In this work, an adaptive method of measuring cylindricity is proposed, the purpose of which is to ensure the required measurement accuracy while reducing the necessary number of cross-sections in which roundness profile measurements should be conducted. The proposed strategy is iterative and it is based on carrying out measurements in the cross-sections of the measured part. The proposed method implies two criteria: the correlation coefficient and the predicted values of the form deviations in the non-measured areas of the measured part. The paper presents the fundamentals of the method and the selected results of its practical verification. The experimental results show the ability of the new method to measure the form deviations of cylindrical parts.

利用圆周截面策略进行自适应圆柱度测量
截面法无疑是应用最广泛的圆柱度测量方法。该方法包括测量圆柱表面多个截面的圆度轮廓。通常,后续截面之间的距离相等。使用的截面数量取决于对圆柱度偏差评估精度的要求。如果只想获得圆柱度偏差的粗略估计,那么可以只在几个截面上进行测量。但是,如果测量精度要求较高,则应在大量横截面上进行测量。在大量截面上进行测量的后果是大大延长了测量时间。在这项工作中,提出了一种测量圆柱度的自适应方法,其目的是确保所需的测量精度,同时减少进行圆度轮廓测量所需的截面数量。所提出的策略是迭代式的,以在被测零件的横截面上进行测量为基础。建议的方法有两个标准:相关系数和被测零件非测量区域的形状偏差预测值。本文介绍了该方法的基本原理及其实际验证的选定结果。实验结果表明,新方法能够测量圆柱形零件的形状偏差。

期刊介绍: The International Journal of Advanced Manufacturing Technology bridges the gap between pure research journals and the more practical publications on advanced manufacturing and systems. It therefore provides an outstanding forum for papers covering applications-based research topics relevant to manufacturing processes, machines and process integration.
