摘　　要：介绍了目前叶片抛光常用的方法,针对现有抛光工艺存在的不足,利用高压磨料水射流技术研究了高效冷态光整加工机制。阐述了3740龙门式数控水切割机床系统构成及工作原理,对牌号为0Cr18Ni9Si的不锈钢在不同入射角下进行了光整加工实验,重点分析了不同射流压力下入射角与表面粗糙度值的变化规律,最后在扫描电镜下观察了不同入射角下工件光整加工区域的表面形貌并进行了分析;其结果表明:磨料水射流对工件光整加工时选择合适的入射角会取得良好的表面加工质量,进而为研制新型的叶片光整加工设备奠定基础。It introduces the commonly methods of leaf blade finishing, being aiming at the shortcomings of polishing process, and studies on the efficient cold polishing mechanism by abrasive water jet technology. Through expounding system composition and working prineiple of 3740 gantry CNC water cutting machine tools, it has a research on 0Crl8Ni9Si stainless steel when the incident angles is different by.finishing experimental method, and there is some intensive analysis on the change regularity of different jet pressure angle and the sucace roughness value; finally, it is to observe the surface morphology of member polishing zone at different incident angles under scanning electron microscope; the results show that selecting a appropriate incident angle can not only get good suace quality when the work piece is finished by abrasive water jet, but also lay, a foundation for developin new type of blade Dolishinz equipment.
