摘　　要：文章对电子行业深孔薄壁铝合金零件的高速切削参数的优化进行了系统研究。文章以去除效率为优化目标,确定了切削参数的优化和切削数据筛选的新方法。首先以切削稳定域理论分析了高速铣削的最大稳定转速及其临界切深,并根据机床功率、切削表面质量、刀具变形和刀具强度等约束条件对切削数据进行理论筛选,根据所提出的理论筛选的数学模型,得到了优化的切削参数。实践表明,文章提出的参数优化和数据筛选方法,可以有效地保证数据高速切削的质量,并显著提高加工效率。In this paper, the study is carried out on the parameters optimization of high speed milling deep hole and thin wall aluminum alloy parts in electronics industry. The material removal rate is chosen as optimization objective. The new cutting process optimization data filtration methods are put forward. Firstly, the maximal maximal spindle rotate speed of high speed machine tool and its critical depth of cutting are confirmed based on the theory of cutting stable region. Secondly, the cutting parameters are filtered with the cutting restraint conditions such as machining tool＇s power, surface quality, cutting tool＇s deformation and strength. The high speed milling parameters are filtered and optimized according to the model set up by this paper. The production practice shows that the method of cutting parameters optimization and filtration can ensure the machining precision and surface quality and improve the machining efficiency obviously.
