Acoustic Emission Signal Through Turning Tools: A Computational Study

There are several mechanisms for the inspection of tool-wear, especially via the Acoustic Emission (AE) method. However, the signals obtained can be affected by the tool geometry, machine vibrations and noise. In this paper wave propagation in cutting tool tools is studied. The purpose is to gain a better perspective of the way that the tool geometry affects the propagated AE signals. This is performed through the Boundary Element Method 2D simulation. More specifically, the time-frequency response of the tool is given in various cases, such as in the coated / uncoated, clamped / unclamped and new / worn tool.
