Özet

Cutting edge geometry and punch wear are closely associated. Punch wear increases past shape errors. These basic defects may be found on the surface of the part and characterise its quality and accuracy. Punch errors are largely associated with punch wear and process parameters. The aim of this study was to investigate the effect of cryogenically treated punches on stainless steel sheet blanking shape errors. For this purpose, the blanking was carried out in a punch machine using 7- and 9-mm-diameter AISI D3 cold work tool steel punches and 1.5-mm-thick AISI 304 austenitic stainless steel sheets. One punch group was subjected to the cryogenic process at -145 A degrees C in addition to the conventional heat treatment. The cryogenic process was carried out to improve the wear resistance and product quality. For this study, punch weight losses were measured and punch wear was evaluated through analysis of SEM and OM images. The rollover depth, burnish depth, fracture depth, burr height and angle of fracture of the selected parts were measured in the specified number of blanks. Results showed that the cryogenic process increased the wear performance of the punches and reduced the shape errors of the parts.
