Friction in Sheet Metalworking

The growing use of coated sheets, aluminum alloy sheets, and coated dies has led to a veritable explosion of publications in the tribology of sheet metalworking. The present paper aims to assess the state of knowledge and provide a starting point for researchers and practitioners alike. Results of potentially valuable work are often difficult to interpret because vital pieces of information are missing. Recommendations are now made regarding the minimum requirements for characterizing the sheet, die, lubricant, and test conditions, and for reporting the results.
