초록
Parts made from CFRP materials are fabricated by hand or using automated layup and forming techniques. Finishing must be performed to meet the requirements for the necessary dimensions and geometry to facilitate assembly with other component parts. Parts such as airplane wings require trimming, milling and drilling to make CFRP into its final shape. In this study, the machining characteristics of CFRP were evaluated by manufacturing an end mill with a changed helix angle of the end mill. The cutting force was the lowest at the helix angle of 60 degrees, but the peeling state of the surface was the best at the point angle of 45 degrees.
