由上海交通大学研究生步丰林进行的理论研究发现，超大厚度切割时，工作液在切维中的流动主要是电极丝移动引起的剪切流动，而喷液时的压差流动是非常小的。研究还发现，增大切维宽度有助于强化剪切流动的作用，实现超大厚度工件的稳定切割；而增大脉冲峰值电流和改良工作液均 According to the theoretical study conducted by Shanghai Jiao Tong University graduate student Bu Fenglin, the flow of the working fluid in the cutting plane is mainly caused by the shear flow caused by the wire electrode movement when the super-thick thickness is cut, and the pressure differential flow during the ejection is very small . The study also found that increasing the width of the cut helps to strengthen the shear flow and achieve a stable cutting of the very large thickness workpiece. Increasing the pulse peak current and improving the working fluid
