The data in this set represents experiments from runs on a milling machine under various operating conditions. In particular, tool wear was investigated (Goebel, 1996) in a regular cut as well as entry cut and exit cut. Data sampled by three different types of sensors (acoustic emission sensor, vibration sensor, current sensor) were acquired at several positions. The data is organized in a 1x167 matlab struct array with fields as shown in Table 1 below

资源包中有.csv文件和.mat两种格式文件 这组数据代表了在不同操作条件下运行的实验。特别是，研究了刀具的磨损情况（Goebel，1996）。采用三种不同类型的传感器（声发射传感器、振动传感器、电流传感器）进行采样数据。数据被组织在一个1x167的matlab结构数组中。
