Abstract

The damaged layer on a ground surface is one of the important criteria for evaluating the surface quality of a workpiece. In the case of an ultra-thin depth grinding (UTDG) a very thin damaged layer has been obtained. A parameter expressing the microstructure of the damaged layer is given by the material density which is related to the acoustic parameter on the material surface. A V(z) curve from which the Rayleigh wave velocity and the total power can be calculated is gotten by using an acoustic microscope. On the basis of the above the damaged layer on a ground surface can be evaluated. KEY WORDS: Ultra-thin depth grinding Damaged layer Material density Evaluation Rayleigh wave V(z) curve 0.
