Стойкость режущих кромок вырубного инструмента при раскрое листовых деталей давлением полиуретана

Abstract

In article authors describe results of researches of influence of obtusion of cutting edges of the cutting tool and other technology factors on parameters of quality of cut down details pressure of a polyurethane. Threshold level of obtusion of the cutting tool is established, outside which repolishing of a surface of the cutting tool is recommended. Results of numerical researches are confirmed by experiments.
