重型机床使用附件铣头后,机床系统刚度有所下降,导致加工精度降低。因此,为使铣头的受力变形在可控的允许范围内,对切削参数进行调整、优化是十分有必要的。运用理论计算、有限元分析和数值拟合相结合的方法,将铣头切削参数与静力变形用关系式量化联系在一起,为铣头切削参数的合理选择提出了一个新的约束标准。 Heavy machine tool attachment attachment milling head, the rigidity of the machine tool system has declined, resulting in reduced processing accuracy. Therefore, in order to make the milling head deformation within the controllable allowable range, the cutting parameters to adjust, optimize is very necessary. By using the methods of theoretical calculation, finite element analysis and numerical fitting, the relationship between the cutting parameters of the milling head and the static deformation is quantified, which provides a new constraint criterion for the reasonable selection of milling head milling parameters.
