The article discusses how to examine torque and angle data collected by power tools during the fastening process. It notes that variation in the fastening process can be identified prior to the assembly of faulty joints once torque and angle data are analyzed. It adds that X-bar and R statistical control charts can be used to analyze torque and angle values. It mentions that such charts can detect problems quickly as they compare samples of data to overall results.
