This study describes the relation between cutting force and surface roughness of a drilled hole wall in small-diameter drilling of GFRP for a printed wiring board. The surface of the drilled hole wall is observed by SEM, and the surface roughness along the feed direction is measured at various rotation angles of the drilled hole. Moreover, the thrust force is measured in order to investigate the characteristics of small-diameter drilling of GFRP. It is found that there are static components and dynamic components in the thrust force. It is shown that the dynamic components are related to the surface roughness of the drilled hole wall.
