In this paper, we present a piece of effective online simulation technology that can be used to design various plastic forming processes. In particular, we have proposed a multi-stage simulation system called QRIS, which enables quick and accurate estimation of the foaming loads involved in each process. We then investigated its potential applications to processing with ultrasonic vibration applied on tools or materials, which is used in many technical fields nowadays to prevent cracking and adhesion by reducing the forming load. First, Common Platform Model (CPM) was constructed based on theoretical understanding of relations between processing conditions and phenomena developed from previous works. Then we carried out multiple simulations to test the accuracy and reliability of the model. The findings from these simulations prove our theoretical models and should form a suitable basis for verifying efficiency throughout the paper.
