1. A power tool comprising:
a pair of jaws configured to crimp a workpiece;
a piston cylinder configured to actuate at least one of the pair of jaws;
a pressure sensor configured to provide pressure signals associated with a crimping application; and
an electronic processor connected to the pressure sensor, the electronic processor configured to:
monitor, while performing the crimping application, a pressure applied by the piston cylinder,
construct a pressure curve indicative of a change in the pressure applied during the crimping application,
process the pressure curve into a vector indicative of one or more features,
evaluate the crimping application based on the vector, and
provide an output indicative of the evaluation.
