摘要: AbstractIn the cold forging industry, tooling makes an important contribution to cost price of forged pieces. Predicting degradation tools would constitute a significant advantage. A possible definition tool life is when roughness parameters formed pieces exceed fixed criteria, at which point must be replaced or polished. In order quantify surface integrity tool, new methodology analysis has been developed by measuring piece. The upsetting sliding test used reproduce contact conditions studied process in laboratory. It allows quantification scatter friction coefficients caused wear, and observations wear surface. An industrial application using AISI M2 steel studied. shown that can predicted workpiece. lifetime o...
