Five-axis NC Machining Process Design of a Precision Pipe Inner Wall Special-shaped Cavity Surface

以某精密管道内壁异形型腔曲面加工为研究对象,加工管道内部空间时存在倒扣区域,刀具易与管道侧壁发生干涉和碰撞等现象,管道内壁异形型腔曲面加工表面质量要求较高,一直是切削加工中的一个难点。本文分析其加工工艺,制定加工方案,利用UG软件CAM模块进行编制加工刀具路径,最后通过Vericut软件进行模拟仿真,优化后管道加工用时仅为52分58秒,提高了管道的加工效率,确保了加工效率和质量,解决了该精密管道内部型腔的加工难题。

The research object is the machining of a precision pipeline inner wall irregular cavity surface.When machining the inner space of the pipeline,there is a reverse area,and the tool is prone to interference and collision with the pipeline side wall.The surface quality requirements for machining the pipeline inner wall irregular cavity surface are high,which has always been a diffi cult point in cutting processing.This article analyzes its machining process,develops a machining plan,and uses the UG software CAM module to program the machining tool path.Finally,simulation is conducted using Vericut software.After optimization,the pipeline machining time is only 52 minutes and 58 seconds,which improves the machining effi ciency of the pipeline,ensures the machining efficiency and quality,and solves the machining problem of the internal cavity of the precision pipeline.
