Abstract
Section titled āAbstractāSuperior performances of carbon fibre-reinforced plastics (CFRP) such as light and higher strength are attracted attention as an alternative material of metal. An application as a printed wiring boards (PWBs) material focuses on its higher thermal conductivity adding to the above properties. The PWBs need so many micro-drilled holes. However, CFRP is well known as one of the difficult-to-cut materials. In the present research, the fundamental micro-drilling phenomena of CFRP were revealed through an experimental approach. This study describes characteristics on micro-drilling, 1 mm or less in diameter, of a CFRP plate using a high-speed spindle. To investigate them, cutting forces such as a thrust force and torque were measured by high-resolution dynamometers and a drill temperature during drilling was monitored by a thermography. In particular, diamond-coated tools were prepared in order to improve tool life. As a result of comparison with conventional non-coated tools, some unique tendencies are revealed. Experimental result shows superior performance of diamond-coated tools for micro-drilling of CFRP.
