Sažetak
Performance of the sheet metal cutting and forming tools producing baking tray parts was monitored. The baking trays are produced from the carbon steel sheet and from the Teflon coated steel sheet, where resistance of the steel substrate of the tool forming inserts against galling is very important, as well as resistance of the cutting inserts to wearing out. The operating inserts were produced from various Uddeholm steels. For the first cutting inserts, Sverker 21 was used, followed by Sleipner steel, both of them uncoated. In order to improve performance, PVD coating (nano-structured TiAlN) was applied on Sleipner substrate. A step forward was using of the powder metallurgy steels, Vanadis 6. The initial forming inserts were made from Vanadis 10 steel, whereas further investigations involved the recently launched steel Vancron 40, a steel type produced specifically for the applications where resistance against galling is a predominant wearing mechanism. The analysis shows that PVD coating provides cost savings due to less frequent tool resharpening. The currently obtained results indicate promising performance of the newly developed steel Vancron 40 for forming applications.
