摘要

铣削颤振是一种非稳定性振动，会损伤工件表面质量，降低切削效率。本文提出了通过理论模型计算与实验设计相结合方法确定铣削颤振稳定域叶瓣图。基于实验测量数据和理论分析计算，利用遗传算法来优化确定各常数参数，从而绘制出与实验测量结果相一致的铣削颤振稳定域叶瓣图。该叶瓣图可有效应用到该机床实际铣削加工过程中的参数选择，对提高铣削加工效率和加工质量有重要意义。

Abstract

The milling chatter is a kind of instability vibration, which usually affects the workpiece surface quality and productivity efficiency. The paper proposed a method to determine the milling stability lobe diagrams based on theory model and experiment design. The genetic algorithm is used to optimize and determine these constant parameters based on measurement data and theory calculation. Then, the stability lobe diagrams can be made to be consistent with the experiment results. So, the stability lobe diagrams can be used to choose the parameters for the milling machine, and it has an importance significant to improve the milling efficiency and process quality.
