2010 PHM Society Conference Data Challenge

There are six individual cutter records, c1…c6, however, the competition only realized c1, c4 and c6 for training.

Each training record contains one “wear” file that lists wear after each cut in 10^-3 mm, and a folder with approximately 300 individual data acquisition files (one for each cut). The data acquisition files are in .csv format, with seven columns, corresponding to:
Column 1: Force (N) in X dimension
Column 2: Force (N) in Y dimension
Column 3: Force (N) in Z dimension
Column 4: Vibration (g) in X dimension
Column 5: Vibration (g) in Y dimension
Column 6: Vibration (g) in Z dimension
Column 7: AE-RMS (V)

Some background on the apparatus and experimental setup can be found here, and in the references in that paper. The spindle speed of the cutter was 10400 RPM; feed rate was 1555 mm/min; Y depth of cut (radial) was 0.125 mm; Z depth of cut (axial) was 0.2 mm. Data was acquired at 50 KHz/channel.
