摘　　要：随着高速铣削技术的发展,铣削过程动力学的传统线性理论已经不能保证所建模型的精确度,而非线性理论可以更好地解释颤振发生、发展和自稳定的全过程.考虑铣削过程非线性因素,是准确预测高速铣削过程中的颤振临界值、工件表面位置误差的前提.从探讨高速铣削过程非线性动力学发展的角度,分析了动力学模型中非线性因素的来源,介绍了非线性铣削系统再生颤振、分叉与混沌的研究进展,并展望了铣削过程非线性动力学的发展趋势.With the development of high-speed milling milling process has been unable to ensure the accuracy of the technology, the traditional linear dynamic theory in founded model. However, nonlinear theory can make clear the whole process of occurrence, blossom and self-stabilizing of the chatter. Considering nonlinear factors in process is the premise of predicting the chatter threshold and surface location error of the workpiece in mill- ing process accurately, in this paper, from the view of discussing the development of nonlinear dynamics in high- speed milling process, the source of nonlinear factors in dynamic models was analyzed, the development of regener- ative chatter, bifurcation and chaos research in nonlinear nonlinear dynamics in milling process was prospected. milling system was introduced, and development trends of
