高速铣削是高性能加工的重要支撑技术,获取无颤振铣削工艺参数是保证铣削加工精度、提高加工效率的前提.再生颤振是引起铣削过程失稳的主要因素,考虑再生效应的动态铣削过程可以表述为含周期系数矩阵的时滞微分方程组.本文从时滞动力系统的动态响应数值求解的角度,对基于动力学模型的铣削颤振稳定性时域(半)解析方法以及应用进行了综述,着重介绍了基于积分方程的半解析方法,并展望了铣削过程稳定性分析的发展趋势.
High-speed milling is an important supporting technology for high-performance machining. Obtaining flutter-free milling process parameters is the premise of guaranteeing milling precision and improving machining efficiency. Regeneration flutter is the main factor causing instability of milling process. Dynamic milling process considering regenerative effect Can be expressed as a system of delay differential equations with periodic matrixs.In this paper, based on the numerical solution of the dynamic response of a time-delay dynamical system, the time-domain (semi-) analytical method and its application to dynamic flutter stability based on dynamic model In this paper, the semi-analytical method based on integral equation is emphatically introduced, and the development trend of the stability analysis of milling process is prospected.
