摘要
研究提出同时考虑薄壳工件及主轴-刀具系统柔性进行切削稳定性预测的方法。分析包含工件动力学特性预测切削稳定性的原理,推导稳定性预测公式。提出考虑工件动力学特性预测切削稳定性的分析流程。以切削薄板类工件为例,采用本文所提出的方法进行实例研究,并分析系统的阻尼、工件的材料参数对切削稳定性的影响规律。
A method for predicting machining stability, considering both the thin-walled worlcpiece and spindle-tool system, was presented. The theory containing the dynamic characteristics of workpiece for stability prediction was analyzed, the stability prediction formula was deduced, and the analysis procedure was provided. Taking a thin plate workpiece as study object, the proposed method was demonstrated. And the effects of the system damping and material parameters ofworkpiece on the machining stability were analyzed.
