平行扫描轨迹间的进给线与层面边界方向一致，可以极大减缓层面加工的台阶效应。
The step effect in the layer manufacturing is improved because the feeding direction is identical with the layer border.
所以，由此产生的机加工痕迹是一条具有很小节距的螺旋线，该节距等于进给。因此机加工表面始终是圆柱形的。
The resulting machining marks are, therefore, a helix having a very small pitch, which is equal to the feed. Consequently, the machined surface is always cylindrical.
同时分析得出，在恒压力进给条件下，随着线锯速度的增加，损伤层厚度略有减小。
It is shown that as feed force is a constant, the damage thickness decreases slightly with the increase of wire speed.
