초록
One of the most important problems in the cutting process of CFRP is tool wear. During CFRP machining, high temperature caused by friction between the cutting tool and the carbon fiber structure increase tool edge wear. Since CFRP is manufactured in a form in which the fibrous tissue is combined with a bonding resin, delamination caused by the separation of the resin and carbon fiber during process is recognized as a very big problem. This delamination proceeds very rapidly as the wear of the drill edge increases. Therefore, in this experiment, tool wear was measured during drilling using a TiAlN-coating drill with excellent wear resistance. In this study, tool wear is measured to suggest optimized cutting conditions for each material.
