Title: Influence of lubricants in deep drawing of thick steel sheets
Author: da Silva, MFLP
Button, ST
Schlechtriem, S
Abstract: The main objective of this was to evaluate the influence of lubrication in deep drawing of EPA sheet with thickness of 3.5 mm and to understand the occurrence of defects as cracks, and bottlenecks. The factorial Design of Experiments was applied to examine the probability of fracture as a function of the following process variables: outer diameter of the blank, radius of the tools, lubricants and performance of the blankholder. Experimental results showed that deep drawing load is significantly reduced with the five different lubricants and that lubrication is more effective when a smaller tool radius is used.
