Due to the late response to process condition changes, forging processes are normally exposed to a large number of defective products. To achieve online process monitoring, multichannel tonnage signals are often collected from the forging press. The tonnage signals contain significant amount of real time information regarding the product and the process conditions. In this paper, a methodology ...

The carbon supersaturated SKD11 punch and core-die were prepared by the plasma carburizing at 673 K for 14.4 ks. upsetting experiment was performed using this to describe plastic flow of pure titanium β-titanium works in higher reduction thickness than 50%. measured load – stroke relationship utilized frictional behavior on contact interface work materials their hardening process. analyzed inve...

Purpose. Production of steel with controlled austenitic transformation during operation the 4Х4Н5М4Ф2 grade (without forging treatment) using technology electroslag remelting and establishing optimal modes heat treatment (annealing, quenching tempering). tools (matrices) from for hot deformation aluminum alloy at operating temperatures below critical point A1.

the forging model for cold rolling is one of rolling models that is used in rolling calculations. in this model,the final rolling pressure is an average value and it is not an accurate model.also by using this model,the firction hill curves are plotted due to the central point of the rolling bite length while frictional stresses intersect at the neutral point.in this study, a new model based on...
