Monitoring surface roughness of thin-walled components from steel C45 machining down and up milling

Article deals with problematic of milling thin wall components, than about study of surface roughness and analytical prediction of surface roughness Rz for variable geometrical parameters. First part is dedicated to research of realized experiments of manufacturing thin wall components, what was basis for designing of experiment. Experiment was conducted in two phases, where first was based on up milling and second on down milling for left and right side of thin wall components with thickness 10 mm. Subsequently, the surface roughness Rz was evaluated and was determinate mathematical equations for each type of milling, side and also for each depth. Final output of presented article is mathematical model of surface roughness Rz prediction for constant cutting conditions, but for variable geometrical parameters of thin wall components with thickness 10 mm.
