| Abstract: | To improve the machining efficiency and surface quality of aeronautical structural parts,a single milling parameter experiment is used to study the effects of cutting parameters(tool,spindle speed,radial milling depth,milling speed)and machining methods(up milling and back milling)on surface roughness.The analysis shows that the surface roughness increases with the increase of tool size and radial cutting depth,but only fluctuates slightly with the increase of milling speed,which is not directly affected by the spindle speed.In addition,the influence of machining methods on surface topography and surface grayscale is analyzed,and the grayscale surface is analyzed by fractal-box dimension method.The result shows that the complexity of surface milling is higher than that of surface milling,which is consistent with the measured surface roughness. |
