Forming process failures

When producing bolts in a forming process, the pressure signals are recorded per forming cycle of a bolt in sampling rate 1000 Hz. The dataset is collected from experiments of different failure modes of a forming process. There are 2 experiments recorded in csv format. Four failure modes, including core broken, cavity block, insufficient lubrication, and material out-of-specification, as well as one normal mode are provided. The first and second groups of experiments were performed in the same machine with different cavities and cores. The data are saved in Forming Failures Exp1 and Exp2, respectively.
