A study is presented of the energy conversion processes to make clear the generation and propagation 'of pressure wave as basic phenomena in underliquid electrical discharge forming. Based on precise observation of electrical and mechanical phenomena, a model is proposed for the process in which the electrical energy released in the electrode gap is converted into the internal energy, the radiation energy of the bubble and the energy. of the pressure wave in turn. The validity of the model is discussed with both the pressure wave measured by the device of special design and the electrical energy. It is shown that the pressure level, the size, and the possible temperature of the bubble and the form of pressure wave in liquid can be reasonably evaluated by the model in the case of a shorter electrode gap. The results present the basis for the analytical design of the systemof uhderliquid electrical discharge forming.
