IMPROVEMENT OF TOOL LIFE IN COLD FORGING

  • Published : 2003.10.01

Abstract

Tool life in cold forging is influenced by tool quality as well as forging conditions and quality of forging material. This paper presents some typical examples of tool life improvement in aspect of tool quality depending on tool design and tool manufacturing parameters. For the purpose of improving tool life, suggestions should be based on accurate understanding of tool operating conditions in cold forging process. FE simulation known as CAE is effective in order to make clear the conditions by some numerically calculated result.
