GH4169高速铣削参数对表面粗糙度影响研究

采用正交试验法,使用整体硬质合金刀具进行GH4169高温合金的高速铣削试验,分析了各切削参数对表面粗糙度的影响规律,建立了表面粗糙度的预测模型,运用方差分析法,检验了模型的显著性。结果表明:每齿进给量对表面粗糙度的影响最大,其次是铣削深度,铣削速度的影响最小。较高的切削速度和较低的进给速度的交互作用对提高表面质量是有利的。

Effect of Milling Parameters on Surface Roughness in High Speed Milling GH4169

The orthogonal experiment is processed for the study on the effect of the cutting parameters on the superalloy GH4169 surface roughness by using the carbide tool on the condition of the high speed milling. The theory model between the surface roughness and cutting parameters is established. The variance analysis is applied to check the significances of the surface roughness prediction model. The research results indicate that feed rate have highly obvious influence on surface roughness, followed by cutting depth and cutting speed, the interaction of the high speed and low feed to improve surface quality is favorable.
