This paper reviews recent progress in metal forming tribology. Tribo-testing methods are chronologically listed, and the correlation among various indices obtained by a compression-twist type tribometer is examined in detail. Results show that clear correlations exist between indices with similar physical meanings. Various factors influencing lubrication mechanisms are discussed, including plastic roughening and its effect on limit strain in the forming limit diagram, the application of the Reynolds equation to rolling, extrusion and drawing lubrication, elasto-hydrodynamic lubrication, micro-plasto-hydrodynamic lubrication, the galling mechanism and temperature analysis. Various lubricants and coating techniques for workpieces are briefly mentioned. Surface treatment techniques for tools such as TD process and Si_3N_4 ceramic provide excellent galling and wear resistance.
