In metal forming processes tribology plays a significant role for process feasibility and tool lifetime. 3rd int. Boundary and mixed lubrication conditions are predominant in metal forming processes. Prod. Process combinations are frequently used and secondary demands placed on lubricants in sheet metal forming operations, including stamping and fineblanking, are often similar. volume 4, pages107–114(2010)Cite this article.

It has been revealed that the usage of certain lubricants leads to higher resistance of the asperity against flattening which would be in favor of reduced friction.

To assess the suitability of lubricants in the case of wet drawing of fine and finest wire, besides the wear phenomenon on the drawing dies and the quality of the wire surface, the frequency of wire cracks is applied.

Boundary and mixed lubrication conditions are predominant in metal forming processes. This work was carried out within the framework of the EC Network of Excellence “Multi-Material Micro Manufacture: Technologies and Applications” (4M). Applying a transparent tool technique the lubrication in plane strip drawing of aluminium sheet is studied providing the strip with surface pockets for entrapment of lubricant.
