摘要

本文对曲面轮廓测量精度进行了分析。由于没有CAD模型或测量细节的其他参考轮廓，第一步是使用技术图纸和公差要求生成凸轮的参考轮廓。测试活动包括三个实验，旨在确定扫描速度对形状偏差δ测量结果的影响，评估偏差δ测量不确定度和测量可重复性。也检查了扫描时间。实验结果验证了所选择的三坐标测量机和测量策略的可行性。测量不确定度不依赖于0.05 ~ 0.2 mm的扫描采样步长，实际测量时间比标称扫描速度的预期时间长30 ~ 40%。

ACCURACY ANALYSIS OF THE CURVED PROFILE MEASUREMENT WITH CMM: A CASE STUDY

In the paper, analysis of the curved profile measurement accuracy is described. Since there was no CAD model or other reference profile for the measured detail, the first step was to generate the reference contour of the cam using the technical drawing and tolerance requirements. The test campaign consisted of three experiments aimed at determining the effect of scanning velocity on the results of form deviation δ measurement, evaluation of deviation δ measurement uncertainty and the measurement repeatability. The scanning time was checked, too. The obtained results demonstrated feasibility of the chosen CMM and measurement strategy. It was found also that the measurement uncertainty did not depend on the scanning sampling step from 0.05 to 0.2 mm, and the true measurement time was for 30-40% longer than that expected from the nominal scanning velocity.
