摘要
当铣削速度提高到常规速度的5~10倍后,铣削过程将变得十分复杂。为此从动力学出发,利用切削理论和数值方法,建立了一个高速铣削的非线性动力学模型。其铣削力模型包括了铣刀的几何特征、铣削力和动态铣削力计算,以及系统动力学方程。并利用吉尔数值法编写了求解程序,程序具有自动变阶和调整步长的特点。利用该模型,可对铣削过程的特征参数如稳定性、切削力等进行预测。
When the speed of milling attains five to ten times the norm, the process becomes extremely complicated. The nonlinear dynamic model for high speed milling was built according as the cutting theory and numerical method. This model includes the geometry character of the milling cutter, milling forces and its calculations, as well as the dynamic equation. The solving program that can automatically adjust steps was programmed with Gear Algorithm. The stability and cutting forces in high speed milling process can be forecasted with the model.
