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
