In this study, COMSOL Multiphysics® software was used to simulate the surface response to excitation method (SuRE). An aluminum beam with a piezoelectric element bonded is modeled using the COMSOL Acoustics Module. A frequency domain sweep study was performed to simulate the sweep sign generation. The frequency spectrum of the structure is monitored through a frequency range of (20kHz-400kHz). A set of probe points measured the response to simulate the experimentations. The changes in spectrums of probe points due to milling, drilling and cutting operations are investigated using sum of squared differences (SSD) method.
