Conclusion
During the calculations, the following values were calculated in this label work:
1. All losses listed Pob = 7.420%; Potr = 0.4%; Pzaj = 4%; Pto = 2.63; Pnc = 0.74%.
2. The efficiency of material consumption at the harvesting stage Kvg = 0.93, At the processing stage Kvt = 0.761 was estimated.
3. Kim makes 0.707 PiPZ Shaft per part, which is 70% of all blanks.
Conclusion: Set by KIM 0.707 is a normal indicator of tk meets the condition KIM > 0.65, but it is worth noting that in small-scale production a smaller 0.65 is allowed. From this, it can be concluded that this rolled stock can be used in large-scale production, the KIM tk is in the tolerance field providing optimal material consumption.
