Abstract
Metallurgical orientation generated by the plastic sliding on the cutting edge produces material anisotropy in both the cutting direction and the feeding direction on a machined surface. This paper deals with the experimental research to evaluate the material anisotropy on the machined surface using a scanning acoustic microscope. A point-focus anisotropic lens, that can be applied for observing an acoustic image, and evaluating an acoustic material signature, was newly developed. Then, material characterization on the end milled surface was carried out. It was made obvious that the Rayleigh wave velocity, measured while rotating the anisotropic lens, showed a periodical change having peak values at the cutting direction and the feeding direction respectively. At the same time, it was made clear that the degree of material anisotropy, the angle of metallurgical orientation and the mean Young's modulus can be evaluated separately through analysing the measured Rayleigh wave velocity.
