摘要。对于车床中旋转物体（如工件）的过程中形状监测，需要具有高时间分辨率的非接触式紧凑型传感器。为了完成这项具有挑战性的任务，我们开发了一种小型化且坚固耐用的非增量干涉式光纤距离传感器，其尺寸仅为30×40×90 mm3，可以将传感器头直接连接到车削刀具钻头的支架上。本文介绍了在金属加工车床上车削零件在加工过程中的三维形状测量结果。为了证明测量结果的准确性，进行了触觉和光学传感器的比较测量。测定径向台阶平均高度时，不同测量方法的最大误差为2.2 μm。
Abstract. For in-process shape monitoring of rotating objects such as workpieces in a turning machine, contactless and compact sensors with high temporal resolution are necessary. For this challenging task, we developed a miniaturized and robust nonincremental interferometric fiber-optical distance sensor with dimensions of only 30×40×90 mm3, which enables attaching the sensor head directly to the mount of a turning tool bit. We present the results of in-process 3-D shape measurements of turning parts at a metal working lathe. To proof the accuracy of the measurement results, comparative measurements with tactile and optical sensors were performed. A maximal deviation between the different measurement methods of 2.2 μm was achieved for the determination of the mean height of a radial step.
