A crimping apparatus includes a ram having crimp tooling for crimping a terminal to a wire during a crimp stroke and a force sensor detecting a crimp force during the crimp stroke. The crimping apparatus also includes a controller that monitors the crimp quality of a crimp based on a frequency profile of the crimp. Optionally, the controller may create the frequency profile based on a force profile using a frequency transform algorithm. The frequency transform algorithm may be a Fast Fourier Transform algorithm.
