.... In tribology, it is more useful to distinguish processes based on the lubricant that can be used. For example, forging or rolling of lead at 25 °C is hot working from a metallurgical standpoint, but a tribologist may consider it to be cold working since liquid lubricants can be used. On the other hand, working...

...Yong Lei; Zhisheng Zhang; Jionghua Jin In multi-operation forging processes, the process fault due to missing parts from dies is a critical concern. The objective of this paper is to develop an effective method for detecting missing parts by using automatic classification of tonnage signals during...

...Lin Yang; Rajiv Shivpuri Lubricants in hot forging are applied to the heated die surface by spraying dilute water based graphite suspensions through high-pressure nozzles. To avoid undesirable steam formation, these lubricant droplets need to completely dry before deformation begins. This paper...

...Timothy A. Perkins; Thomas J. Kronenberger; John T. Roth Manufacturing processes (e.g., forging, rolling, extrusion, and forming) rely on heat to reduce the forces associated with fabricating parts. However, due to the negative implications associated with hot working, another more efficient means...

...Yuhong Liu; Fuguo Li; Shuxin Wang; S. Jack Hu In a material hot forging process, rational preform design not only ensures that metal flows properly in die cavity and that final products have excellent quality, but also reduces tooling cost. In the present work, it is proved in theory...

...Jihyun Kim; Qiang Huang; Jianjun Shi; Tzyy-Shuh Chang 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...
