摘要
分析了国内外有关薄壁件铣削加工力学模型、动态特性及加工变形的研究现状;在已有文献基础上建立了侧壁铣削加工动力学分析有限元模型,并通过试验对模型进行了验证;以建立的模型为基础,进行了大量有限元模拟分析,并对结果进行了讨论。结果表明,在一定范围内提高转速有利于减小薄壁件加工变形,提高加工精度。
The existent studies on the cutting force model,dynamics properties and machining air crafts of the thin-walled structure components are reviewed.Then the dynamics analysis model is present ed and verified experimentally.Based on the model,much FEM analysis has been carried out.At last,th analysis results were concluded.It is shown that increasing the rotation speed of the cutter in certain range is helpful to decrease the machining errors and ensure the machining precision.
