Abstract
A rivet monitoring system is provided which has a micro-strain or micro fluid pressure sensor that measures strains or pressures within a tool component. These measured signals are compared to a number of tolerance bands formed about median strain or pressure versus time curve. Various techniques are provided to analyze the measured data with respect to the tolerance bands to determine if a particular rivet set is acceptable.
