变速铣削稳定性预测的整体离散算法
Stability Prediction of Milling with Periodic Spindle Speed Modulation based on Global Discrete Algorithm
摘要
Abstract
In the milling process, chatter always results in poor workpiece surface smoothness, tool wear, and other potential damage which reduce the productive efficiency and the accuracy of the workpiece processing. The regenerative chatter is the most common chatter in the actual milling process. An effective method to avoid the chatter is to change the spindle speed periodically. In this paper, a novel discretization method based on the regenerative principle is proposed to predict the stability of the variable speed milling. The differential terms of the solution is used through the matrix reconstruction. The results show that the proposed method can reduce the computation time and improve the accuracy of the solution.关键词
