Abstract
One of the quality assurance methods for steel and composite materials is to verify material constitutes and structures of polished specimens by microscope. We prepared a sample used for microscope analysis in the following method: first, cut a sample from the cross-section, and mount with the epoxy resin, and then grind it. This process requires long craftsmen’s experience to grind a sample properly for microscope test. In this research, we comparably evaluated the differences in grinding sound and comprehension skills between the expert and the non-expert. As a result, we found that the expert was more sensitive to the difference in the sounds generated during grinding process. He comprehended the state of a grinding sample by the sound generated during grinding and adjusted his grinding force in a wider range.
