The Influence of Eccentricity on Thrust Force of Helical Milling in Carbon Fiber Composite Holemaking

Abstract:

Carbon fiber composite is widely used in aerospace and aircraft industries because of their remarkable advantages such as lightweight and high strength. As an effective holemaking technology, helical milling is widely used in machining carbon fiber composite material recently. In this paper, the mathematics modeling of tool motion in helical milling is studied and simulated; the effect of eccentricity on helical milling is analyzed and tested by experiment. From the analysis and experiment, a conclusion is drawn that: using a smaller diameter tool and larger eccentricity cause a decrease in thrust force and an improvement in delamination defects.
