激光电化学复合加工的冲击空化检测及试验
Detection and experiment of shock cavitations of laser electrochemical composite processing
摘要
Abstract
In order to measure the sound pressure signals generated by the breakdown of pulse laser through the electrolyte and discuss the impact and influence of shock cavitations on laser electrochemical composite processing , a laser electrochemical composite processing detection system was established .At first, the sound pressure signal was stored with an oscilloscope and the acoustic pressure and waveform was analyzed and calculated with the XVIEWER software .Then, pictures of the composite laser electrochemical machining area were taken and the effect of cavitations on laser -electrochemical machining area ’ s the characteristics morphology and surface quality was analyzed .The experimental results indicate that because pulsed laser is focused in the electrolyte , cavitations effect is generated and three different sound pressure signals are radiated .With the increase of laser energy , three acoustic pressures of laser-induced shock cavitations increase and the radius and energy of laser-induced bubble increase .In the applications of laser electrochemical machine , when the laser energy increases , the laser plasma shock wave and jet force will improve and the material removal will increase .Meanwhile bubble oscillation promotes the electrolyte flow , it plays a key role on the morphology of the processing area and surface quality .The result is very useful for complex machining process and morphology .关键词
