Outline of Final Research Achievements

We advanced the technology development of metal production process of complex shaping and stable quality by fusion of casting process and advanced system control / information engineering technology. In order to compensate for quality stability in response to fluctuations in metal temperature, viscous flow and volume, we constructed an adaptive filling control system by force sensor information processing. The filling behavior of the liquid inside the mold can be estimated and the filling rate is then automatically adjustable to improve the casting quality. Experiments on metal pressurized filling had been carried out and the effectiveness of the proposed method was evaluated.
