Forming process failures

When producing bolts in a forming process, the pressure signals are recorded per forming cycle of a bolt. The dataset is collected from experiments of different failure modes of a forming machine. Two experiments were 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 two experiments were performed in the same machine with different cavities and cores, and saved in Forming Failures Exp1 and Exp2, respectively.
