Abstract

The objective of this research is to study the effect of the fluid mandrel on the reduction of area, drawing stress and thickness in copper tube drawing process. The standard copper tube JIS C12200 with 15.88 mm diameter and 1.12 mm wall thickness is choosen for this experimental investigation. Two types of fluid mandrel, water and lubrication oil (SAE20W40) were contained in the copper tube. The copper tube is drawn through the die (a = 15°) by using the area reduction of  20, 35 and 50% with the drawing speeds at 5 and 30 mm/min. The results shown the influence of  the fluid mandrel on the reduction of area, the tube thickness and the drawing stress and also depend on the density of fluid and the drawing speed.
