Lubrication Influence In The Drawing Process Of Aluminum, Steel And Copper Alloys

This work aims to investigate the influence of lubricant types (solid, liquid and paste) in drawing process of metallic bars, using aluminum, copper and steel alloys with an initial diameter of 15.88 mm and, after the process, a final diameter of 14.87 mm, corresponding to a reduction of 6.36%. The evaluated parameters correspond to surface roughness and microhardness. The found results were assessed by statistical calculations of average and standard deviation.
