Signal Segmentation for Milling Process

This dataset is used to develop an algorithm for automatic segmenting the collected signals. When machining a workpiece in a milling process, vibration signals can be recorded by a 3-axis accelerometer, which is attached on the spindle of a CNC milling machine. To segment the recorded signals, a moving window (0.5 sec) is applied to sample the vibration signals and manually labeled the corresponding modes, i.e. dry run or milling, of each window. To verify the algorithm, 3 types of operations are provided and recorded in csv format.

本数据集用于研发面向采集信号自动分割的算法。在铣削加工工件的过程中，可通过安装于CNC铣床主轴的三轴加速度计（3-axis accelerometer）采集振动信号。为实现采集信号的分割，本数据集采用时长为0.5秒的移动窗口对振动信号进行采样，并为每个窗口对应的加工模式（即空运行或铣削）完成人工标注。为验证所研发的算法，本数据集包含3类加工操作的采集数据，并以逗号分隔值（CSV）格式存储。
