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