| Outline of Final Research Achievements |
The purpose of this study is to develop the high efficiency deburring method for polystyrene (PS) burr on the resin injection molding by the underwater shock wave loading inducued by the electrical discharge to the burr attached with the microbubbles. The optimum radius of microbubble subjected by the underwater shock wave causing the disintegration of PS burr was researched theoritically. The fragmentation of PS thin plate attached with the microbubbles simulating the burr by the underwater shock wave loading was visualized. We clarified the optimum conditions causing the fragmentation was that the microbubble was attached to the bottome of PS plate setin the water that was the water-backed plate moddel from the visualization results. From these results, the deburring method using the microbubbles subjected to the underwater shock wave loading was established.
