CFRP 직물형 90도 배열 적층 프리프레그의 회전수 변화에 따른 HSS, TiAIN 드릴 절삭에 관한 연구 A Study on HSS, TiAIN Drilling According to the Change of Rotation Speed of CFRP Fabric Type 90 Degree Stacked Arrangement Prepreg

Demand for CFRP with new characteristics is increasing in various industrial fields, from parts materials to daily necessities, and research on this is also being actively conducted. CFRP is a material that realizes properties suitable for multiple functions that cannot be seen in a single material by physically combining two or more materials with different shapes and chemical compositions. When machining CFRP using a high-speed steel (HSS) drill or a TiAlN-coating drill with different rotation speed and feed speed, the cutting force was experimentally analyzed and the optimal tool material and cutting conditions were selected. The cutting force according to the change in rotation speed of the high-speed steel drill and the TiAlN-coating drill is compared.
