摘要
高强度铝合金广泛应用于飞机结构件中,加工时去除量大,在提高加工效率的同时保持良好的表面质量是工艺设计中的难点。为了研究高速切削中各加工参数对切削负载和切削质量的影响,设计了五因素四水平的正交试验,测量了切削负载和加工表面粗糙度,并进行了极差分析。研究结果表明,高转速、大切削深度和小切削宽度的参数组合能够获得较高的材料去除效率、较高的表面质量和装夹适应能力。
High-strength aluminum alloys are widely used in aircraft structural parts,and the amount of material removed 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 combination of high speed,large depth of cut and small cutting width can achieve high material removal efficiency with high surface quality and clamping adaptability.
