摘要
为了分析切削参数对工件表面粗糙度的影响规律,首先借助Deform-3D软件模拟出不同切削参数下铝合金工件的表面粗糙度值;其次采用二次响应曲面(RSM)法建立6061铝合金经高速铣削后的表面粗糙度预测模型并对模型的真实性进行显著性分析,分析铣削参数对工件表面粗糙度的影响;最后通过切削试验对仿真结果进行验证并得出最优参数组合。结果表明:在试验条件下,对6061铝合金铣削表面粗糙度影响的重要程度依次为背吃刀量>主轴转速>每齿进给量。
In order to analyze the influence of cutting parameters on surface roughness,it simulates the surface roughness under different cutting process parameters with the help of Deform-3D,applies the response surface methodology to establish models for predicting the surface roughness of 6061 aluminum alloy in high-speed milling.It analyzes the significance of the model's authenticity and the impact of milling parameter upon the surface roughness,takes cutting experiments to verify the simulation data.The results show that the importance of 6063 aluminum alloy milling surface roughness degree are back to feed amount,spindle speed per tooth in turn under the experimental conditions.
