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
