Abstract To solve the vibration problem during the edge trimming of thin-walled composite component with V-shape, and to explore the influence of cutting parameters on cutting force and workpiece vibration, experiments are designed based on the central composite response surface method in this study. The effects of spindle speed, feed rate, and cutting depth on cutting force and vibration acceleration are explored, and prediction models for cutting force and vibration acceleration are established. The optimal cutting parameters are obtained with the lowest cutting force and lowest vibration acceleration as optimization goals, which are spindle speed of 6000 r/min, feed rate of 400 mm/min and cutting depth of 1.4 mm. Research results of this study will help guide the selection of edge trimming parameters for thin-walled composite components with V-shape, so as to reduce vibration and improve surface quality during machining.
