PRESSED DIE LIFETIME PREDICTION PROGRAM AND DIE MATERIAL DESIGN SUPPORT PROGRAM

摘要

PROBLEM TO BE SOLVED: To provide a pressed die lifetime prediction program which enables improving the prediction accuracy of die lifetime. Ž

SOLUTION: The proposed pressed die lifetime prediction program uses a storing part which associates a die material type with constants A, α and β, and calculates the number Nfof shots up to destruction by a prediction equation: Nf=A×exp(-(ασ+βa)) with respect to an inputted die material (S1), load stress σ, and a second-phase particle size a (S2).
