Abstract：

For the problem of low precision in the numerical simulation of the incremental forming, with the ratio of kinetic energy to internal energy less than 5% and the error of thickness less than 3% proposed as a set of criterion, the numerical simulation and experiment were adopted in the study. Taking cone part as an example, the influence of virtual forming speed on the precision in the numerical simulation of incremental forming was investigated. The results show that the virtual forming speed has a greater impact on the precision of numerical simulation, excessive virtual forming speed can reduce the precision in numerical simulation. Although slow virtual forming speed can improve numerical simulation precision, the numerical simulation efficiency will be reduced. When the virtual forming speed is at 800 mm·s-1, the precision of numerical simulation can be ensured and numerical simulation efficiency can be improved as well.
