[Larger slab][Optimal Design]Open-die forging of larger slab
An open-die forging process of larger slab was simulated to conduct process design optimization to increase product quality as well as yield rate. Fig. shows a typical example, which consists of about 300 blows. The simulation was conducted in semi-automatic way, i.e., user-intervention is made only when material adjustment is needed, for example, rotating and…
Read MoreAnalysis of multi-stage hollow shaft swaging process
An analysis of the 5-stage hollow shaft swaging process was made. In this process, the change of the thickness is very high in the first and second stages. The position of the workpiece is controlled by the mandrel in the first and second stages and pusher controlled the workpiece motion in the third stage. Above…

Read MoreNew grip model
Recently a grip model for roll forging was improved. With the new grip model, we can apply pulling force to the material, which is proportional to the roll separating force. Of course, The maximum pulling force by some limited value given by users can be constrained. With this model, more stable and accurate predictions could…
