Abstract 

When producing bolts in a cold forging process, the pressure signals are recorded per cycle of forming a 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.

Instructions: 
  • Domain: cold bolt forging process
  • source: pressure sensor
  • Sampling rate: 1000 Hz
  • Target: failure classification
  • Failure modes:
    • 1. Normal: normal production.
    • 2. Cavity Block: a cavity was blocked with different heights of bumps.
    • 3. Core Broken: a core being broken into three levels
    • 4. Insufficient Lubrication: insufficient lubrication in two levels.
    • 5. Material out-of-specification: the materials being shorter or longer.
  • Total files: 2 
  • File format: csv
  • Description of fields in each file
    • TimeTag: experimental recording time of each producing cycle.
    • Label: faliure mode
    • Rawdata1-Rawdata386: pressure data collected by each bolt forming in a sampling rate 1000 Hz. 1-386 means it takes 0.386 sec to finish a bolt forming cycle, and their values stand for the raw data without standardization.
