为验证激光加热辅助技术改善引弧微爆炸加工质量和提高加工效率的可行性,探索加工工艺参数对加工过程的影响规律,设计了激光加热辅助引弧微爆炸加工试验系统,并通过试验研究了工艺参数对材料去除率和崩碎的影响规律。试验结果表明:激光加热辅助引弧微爆炸加工陶瓷可以提高材料去除率,改善崩碎情况;加工效率随激光功率的增加而提高,随光斑尺寸的增大而降低,随距离的增加先提高后降低;崩碎随激光功率的增加而减少,随光斑尺寸的增大先减少后增多,随距离的增加先减少后增多。研究结果为激光加热辅助引弧微爆炸加工机理的研究和工艺参数的优化提供了参考依据。
In order to verify the feasibility of laser assisted heating technology to improve the quality of arc-ignition micro-explosion processing and improve the processing efficiency, the influence rule of processing parameters on the processing is explored. The laser-assisted auxiliary arc ignition micro-explosion processing test system is designed. Effect of Process Parameters on Material Removal and Crushing. The experimental results show that laser-assisted arc ignition micro-explosion processing of ceramic can improve the material removal rate and improve the crushing situation; the processing efficiency increases with the increase of laser power, decreases with the increase of spot size, and increases with the increase of distance Decrease with the increase of laser power. The collapse and collapse decrease first and then increase with the increase of laser spot size, then decrease and then increase with the distance increasing. The results provide a reference for the research of laser heating auxiliary arc micro-explosion processing mechanism and the optimization of process parameters.
