Abstract

Une unité de calcul de degré d'usure cumulatif (205) calcule le degré d'usure des bords de coupe d'un poinçon et d'une matrice lorsqu'une machine à poinçonner (1) traite une fois un métal en feuille avec un ensemble de matrices du poinçon et de la matrice, et calcule le degré d'usure cumulatif des bords de coupe du poinçon et de la matrice par accumulation du degré d'usure de chacune des fois que la machine à poinçonner (1) traite le métal en feuille plus d'une fois avec l'ensemble de matrices. L'unité (208) de gestion d'informations de gestion de matrice amène une unité (209) de stockage d'informations de gestion de matrice à stocker des informations de gestion de matrice qui associent un code d'identification de matrice fourni à chaque poinçon et matrice au degré d'usure cumulatif calculé par l'unité de calcul de degré d'usure cumulatif (205). Après avoir reçu des informations d'enregistrement de rectification indiquant qu'une meuleuse à rectifier les matrices (3) a rectifié un bord de coupe du poinçon ou de la matrice, l'unité (208) de gestion d'informations (208) efface le degré d'usure cumulatif stocké en association avec le code d'identification de matrice du poinçon ou de la matrice qui a été rectifé-e.
