Establishing the effectiveness of a lubricant in the deep drawing process by means of prior loading duration variation

Abstract

With the many different lubricants available for similar purposes today, the choice that the engineer must make is often based on arbitrary assumptions or confined to personal experience. In the present paper, the authors present a new technique of determining the suitability of potential lubricants for the deep drawing process. The technique is also applicable to many metal forming processes where lubricant selection is critical to the success of the operation.
