高速走丝线切割导轮动态特性及定位方式对加工的影响

本文采用有限差分方程,用计算机模拟分析了导轮跳动对电极丝动态位置的影响,结果表明:电极丝的振幅随导轮跳动频率上升而增加。文中还对各种定位限幅方式进行了工艺比较,设计出一种较为方便实用的定位限幅器。

In this paper, with computer simulation, the affection of the guide wheel pulsation on the dynamic position of the electrode wire is analysed by using finite difference equation. The result shows that the amplitude of the wire is in direct proportion to the pulsation frequency. The authors compare different kinds of location pattern and design a kind of practical and convenient Guide.
