0Cr18Ni9不锈钢焊缝高速铣削表面粗糙度试验研究

Experimental investigation of surface roughness in high-speed milling weld seam of 0Cr18Ni9

采用正交试验方法进行0Cr18Ni9不锈钢焊缝高速铣削试验,分析铣削参数对表面粗糙度的影响规律,并建立表面粗糙度的经验预测模型。结果表明:随着主轴转速的增大,表面粗糙度值减小,而随着进给速度、切削深度的增大,表面粗糙度值增大,进给速度对表面粗糙度的影响较为明显;较高的主轴转速和较低的进给速度的交互作用有利于减小表面粗糙度值,提高表面质量。

The orthogonal experiment is processed for the study on the effect of the milling parameters on the weld seam of 0Cr18Ni9 surface roughness by the high speed milling .The empirical prediction model between the surface roughness and milling parameters is established .The research results indicate that the surface roughness decreases with the higher spindle speed ,but in-creases with the larger feed rate and cutting depth ,the feed rate has highly obvious influence .The interaction of the high spindle speed and low feed rate is favorable to reduce surface roughness and improve surface quality .
