Optimization of micro milling processing parameters for SLM Inconel 718
Selected Laser Melting(SLM)Inconel 718 formed parts are widely used in aerospace,automotive rail transit,and petrochemical industries,but their surface accuracy is poor and needs to be improved through cutting.Focusing on optimizing surface roughness,a three-factor four-level micro milling orthogonal experiment was conducted with spindle speed,cutting depth,and feed rate per tooth as variables.The significance of the influence of spindle speed,cutting depth,and feed rate per tooth on surface roughness was studied through range analysis.The results showed that under processing parameters of n=15 000 r/min,ap=60 μm,and f=1 μm/z,the surface roughness value of SLM formed parts was the lowest.The optimized parameter combination provides a certain reference for the micro milling processing of SLM Inconel 718.
