摘要:
针对激光打孔表面具有再铸层、微裂纹等工艺缺陷,提出了喷射液束电解辅助激光加工复合加工工艺.在对喷射液束中激光加工和喷射液束电解加工进行机理分析的基础上,建立了复合加工模型,研制了专用试验装置后对1Cr18Ni9Ti不锈钢进行打孔试验,采用形貌仪和扫描电子显微镜对试验结果进行了分析.结果表明:喷射液束电解辅助激光加工的小孔形状与加工模型的结果相一致; 复合加工中电解对激光打孔入口处的孔壁再铸层由0.031 mm减小至0 mm,孔底再铸层由0.019 mm减小至0.017 mm; 电解作用能消除激光加工产生的微裂纹,提高激光加工的表面质量.
Abstract:
A new hybrid process of laser beam machining assisted by jet electrochemical machining(LBM-JECM)is proposed to deal with the metallurgical defects of recast layer and micro crack in laser beam machining. Based on mechanism analysis of laser beam machining and jet electrochemical machining, a processing model of LBM-JECM is built. The special experimental equipments were designed and made. Drilling experiments on the stainless steel 1Cr18Ni9Ti were conducted with the equipments, and the holes were studied by using surface topography instrument and the scanning electronic microscopy(SEM). The results show that theoretical model and experimental results conform well with each other. During LBM-JECM, electrolysis can reduced the hole wall recast layer from 0.031 to 0 mm at the entrance, and from 0.019 to 0.017 mm at hole bottom. Electrolysis eliminates the micro crack, and improves the surface quality of laser beam machining.
