Research on Machinability of the Shell Materials and Tools' Failure

Abstract:

Large cylindrical shell is a large diameter and thick wall tube part working in high temperature and high pressure environment. It is made of 2.25Cr-1Mo-0.25V high strength steel, whose machinability is special. The characteristics of cutting temperature and cutting force are researched in the cutting process by analyzing the machinability of 2.25Cr-1Mo-0.25V steel in this paper. And the main tool failure modes are analyzed in the cutting process, combining with empirical approach to compare tool failure modes under cutting different steels. The high efficiency cutting measures are proposed in tool optimization design finally, in order to provide a reference for high efficiency machining of large cylindrical materials.
