NX后处理技术在圆柱壳体零件加工中的逆向应用
|
摘要
为避免加工过程中刀具或角度头与壳体内壁发生碰撞干涉,提取壳体内壁上的特征曲线,修改后作为生成中间刀轨的封闭边界。通过创建中间后处理器,将中间刀轨转化为仅含有点坐标的文件,利用该文件构建曲线,并将曲线缠绕于壳体内壁,最后采用可变轮廓铣中的曲线/点驱动方法创建用于加工壳体内壁的刀轨。结果表明,此方法在加工壳体内壁时可以有效的减少抬刀,避免刀具或角度头与壳体内壁发生碰撞干涉。
In order to avoid collision and interference between the tool or angle head and the inner wall of the shell during machining,the characteristic curve of the inner wall of the shell was extracted and modified as a closed boundary for the formation of intermediate tool path.By creating the middle post-processor,the intermediate tool path was converted into the file containing only point coordinates,and the curve was constructed by using the file,and the curve was wound on the inner wall of the shell.Finally,the tool path for machining the inner wall of the shell was created by using the curve/point driving method in the variable contour milling.The application results show that this method can effectively reduce the lifting tool when machining the inner wall of the shell,avoiding collision and interference between the tool or the angle head and the inner wall of the shell.
