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.
