摘　　要：微细管电极铣削微沟槽加工工艺受到多种加工参数的共同影响,通过科学的工具深入探究、量化和总结这些规律是后续理论研究的基础,对于实际工程问题的研究至关重要。微沟槽加工的定域性是衡量微细管电极电解铣工艺的重要评判标准,而加工参数的选取对微沟槽加工的定域性起到决定性作用。通过皮尔逊相关性分析法探究管电极电解铣削微沟槽工艺主要加工参数与槽宽的相关性,发现电流密度的影响力显著高于初始加工间隙和走刀速度,并制定出加工参数的调整策略,实现了高定域性微沟槽加工的参数快速优选。The micro groove machining process of micro tube electrode milling is affected by a variety of processing parameters.It is the basis of theoretical research to explore,quantify and summarize these laws through scientific tools,which is very important for the research of practical engineering problems.The locality of micro groove machining is an important criterion to evaluate the electrochemical milling process of micro tube electrode,and the selection of machining parameters plays a decisive role in the localization of micro groove machining.In this paper,Pearson correlation analysis method is used to explore the correlation of the main processing parameters and the groove width.It is discovered that the influence of current density is significantly higher than the initial machining gap and cathode scanning speed.Based on that,the adjustment strategy of each processing parameter is formulated.Thus,the parameters of high locality micro-groove machining can be optimized quickly.
