The Improvement of Casing Premium Connection Machining Method
Premium connection has high quality requirements on thread and sealing surface and needs to be machined by CNC lathe.Using loop program in CNC machining has advantages in reducing memory occupying, cutting the computational procedure and simplifying program.However, the processing profile curve often has a special shape.As a result, the idle motion of tools is increased and the production efficiency would be lowed.The paper studies the two procedures of rough turning process and finish turning process in a new gas tight premium connection machining.An improved method is developed by which the idle motion of tools is reduced and the machining efficiency is improved.The good result in the field application indicates that the improved method is practical.
