Forming process failures

When producing bolts in a cold forging process, the pressure signals are recorded per cycle of forming bolt. The dataset is collected from experiments of different failure modes of a forming machine. Two experiments were recorded in csv format for providing four failure modes, including core broken, cavity block, insufficient lubrication, and material out-of-specification, as well as one normal mode. The two experiments were performed in the same machine with different cavities and cores, and saved in Experimental Data for Modeling and Testing.在冷锻工艺生产螺栓的过程中，会针对螺栓成型的每个循环周期记录压力信号。本数据集采集自某成型机不同失效模式下的成型实验。本次实验共开展两组，以逗号分隔值（CSV）格式存储数据，涵盖四种失效模式：芯杆断裂、型腔堵塞、润滑不足以及材料规格不符，同时包含一种正常工况。两组实验均在同一台成型机上开展，仅更换了不同的型腔与芯杆，所有实验数据均存储于建模与测试实验数据（Experimental Data for Modeling and Testing）目录中。
