In this study, we developed a cylindrical electrodeposited diamond mesh grinding wheel for machining large-diameter holes (80 and 160 mm in diameter) in CFRP plates. This tool differs from a general hole saw in that it can also be used on the sides, and can even finish the hole wall surface by taking advantage of its high chip discharge performance due to the wire mesh base metal. When using the side face of this wheel, the main machining is performed at points of wire crossing where the radial protrusion is large, but a smooth surface can be obtained by tracing the hole contour while oscillating the tool up and down. After repeated finishing operations without increasing the depth of cut, the difference from the target dimension becomes as small as approximately 0.02 mm, indicating that the surface roughness meets the standard values for aircraft parts.
