interference free meaning in English

无干扰的

The first one is based on the offset surface of subdivision model . through mapping the original mesh node by node , the offset surface is generated . it can get the interference free tool - path directly from the offset surface without complex interference check and process
然后实现了两种精加工刀具轨迹生成方法,一种是基于等距面的截平面法,通过点对点法向映射的方法生成递归分割曲面模型法向等距面,由该等距面生成无干涉刀具轨迹。
In order to generate tool - path quickly , another method is presented . it can generate interference free tool - path directly from the section line of the triangulated surface model . search each vertex of the model to get the triangles which may be interfered using the radius of the cutter
为了解决这一问题,本文又提出了基于加工曲面的截平面法,通过刀具投影和曲面模型节点坐标的位置关系确定可能发生干涉的小三角片的集合,以加快干涉检测的速度,然后在这个集合上生成无干涉刀位点。
