Abstract

Abstract: In order to reduce delamination and other damages during milling of carbon fiber reinforced composite (CFRP), improve its service life and production efficiency, the experiment of milling CFRP unidirectional laminates along various fiber angles (θ) was carried out by MV80 three-axis CNC machining centers. Based on the single factor experimental method, the influence of fiber angle and milling parameters on milling force and milling surface quality was studied. The results show that the main milling force is positively correlated with fiber angle at<90°, and negatively correlated with fiber angle at>90°; as the spindle speed increases, the main milling force decreases, and the main milling force increases with the increase of milling depth and feed rate per tooth; in different fiber directions, the surface roughness of CFRP decreases with the increase of spindle speed, but increases with the increase of milling depth and feed rate per tooth. When the fiber angle is 90°, the surface quality is optimal. The weight of milling force affected by different parameters is analyzed by orthogonal experiment. The results show that the fiber angle is the most important factor, followed by milling depth. And a mathematical model for milling force processing was constructed through linear regression of experimental data, aiming to provide a certain reference basis for optimizing processing parameters and digital processing of carbon fiber epoxy resin based composite.

Key words: CFRP, milling force, fiber angle, milling parameters
