| Research Abstract |
Sharpening cutting-edge of thick diamond-film brazed tool to make wood cutting tool with sharp cutting-edge and long tool-life was taken note of in this study. The diamond-film brazed tool was made, it was confirmed that cutting-edge roundness of the tool became small and its surface became flat as compared with the diamond-coated tool. Cutting tests for the edge-sharpened thick diamond-film brazed tool, diamond-coated tool and uncoated tool in the milling of thirteen kinds of woods and three kinds of wood-based materials with a spindle shaper were performed, the difference in cutting power consumption by tool for each work material was examined and the value for cutting-edge of thick diamond-film brazed tool was compared with those for other tools. Furthermore tool-life tests for three tools in the milling of melapi or MDF were performed, the difference in tool-wear progression by tool was examined. From the results of cutting test, cutting performance of the edge-sharpened thick diamond-film brazed milling tool was examined and the superiority as the milling tool was clarified from the view point of long tool-life.
