This paper discusses the effect of sheet anisotropy on the springback of stainless steel 410 draw-bend specimens. The role that the anisotropy plays in the springback is assessed experimentally as well as through finite element simulations. Process conditions, such as blank holding force, have an obvious effect on springback. Experiments and simulations are conducted with varying blank holding force to assess its role in springback of the formed part. The blank holding effect can also be varied by modifying the contact conditions between the specimen and the die. In this work we consider the effect of lubrication as a means to reduce the coefficient of friction between the contacting surfaces. The role of lubrication has an effect similar to reducing the clamping force. The role of the lubrication on springback is also addressed in this work by comparison to results of dry contact conditions.
