电极丝在加工过程中受各种力的作用会发生形位变化 ,直接影响加工精度和加工稳定性。本文通过实验分析 ,研究了电极丝的形位变化规律 ,并提出了稳定电极丝形位的有关措施 Electrode wire in the processing by the role of a variety of forces will occur morphological changes directly affect the processing accuracy and processing stability. In this paper, through experimental analysis, we study the change rule of the shape of the electrode wire and put forward some measures to stabilize the electrode shape of the electrode
