Abstract
A system for evaluating integrity of a cutting blade includes at least one stress wave generator for generating at least one stress wave in a cutting blade under test. A sensor detects a signal generated by the at least one stress wave. An integrity analyzer coupled to the sensor determines an indication of integrity of the cutting blade based on at least one characteristic of the signal.
