摘要
针对新型轻量化航空结构材料铝锂合金的高速切削加工,研究分析了切削速度和每齿进给量对其切削力的影响规律,同时对高速铣削铝锂合金、7085、6061和Ly12过程中的切削力进行了对比试验研究。试验结果表明,高速铣削铝锂合金时,随着每齿进给量的提高,切削力显著增大;随着切削速度的提高,切削力变化趋势并不明显,呈现出先稍有增大后又逐渐减小的趋势;高速铣削铝锂合金与高速铣削7085、6061和Ly12时的切削力变化规律相似,数值接近。
An experimental study of influence of the cutting parameters including cutting speed and feed per tooth on the cutting forces in high speed peripheral milling of new aeronautical material Aluminum-Lithium alloy is presented. Meanwhile, contrast experiments of cutting forces in high speed milling of Aluminum-Lithium alloy, 7085, 6061 and Ly12 are carried out. The experimental results show that the cutting forces increase linearly as the feed per tooth increases. However, as the cutting speed increases, the cutting tbrces increase firstly and then decrease; In addition, the changing rules of cutting tbrces in milling of Aluminum-Lithium alloy, 7085, 6061 and Lyl2 are similar and the numerical sizes of cutting forces are close.
