ABSTRACT
The aim of the present study is to give for the turret punch press users a methodology to quantify the critical tools wear and help to identify the best procedure of sharpening, applied to the particularities and needs of each specific application for this equipment. The process of quantifying the control parameters of the tools sharpening is linked to the control of the rounding increment on the cut edge, in relation to the amount of hits executed. There are a series of published information about the subject, with recommendations and results of specific studies that can be used as a guide to the users in their own maintenance plans. An experimental test, easy to be done, which can be repeated and updated in metallurgical industry, quantify and identify the correct sharpening time, considering specific conditions. The methodology here presented can be
