High-strength aluminum alloys are widely used in aircraft structural parts,and the amount of material re-moved during cutting is usually large.Improving machining efficiency while maintaining good surface quality is a difficult task in process design.In order to investigate the effect of each machining parameter on cutting load and cutting quality in high-speed cutting,a five-factor,four-level orthogonal test is designed in this study.The cutting load and machined surface roughness are measured in the experiment,and the extreme difference analysis is performed.The results show that the com-bination of high speed,large depth of cut and small cutting width can achieve high material removal efficiency with high sur-face quality and clamping adaptability.
