Paper Title:
Research on Adhesion Failure of Milling Insert and Mechanical-Thermal Coupled Field in Milling of Difficult-to-Cut Materials
  Abstract

The measuring temperature and force experiments of cutting heat-resistance steel (3Cr-1Mo-1/4V alloy and 1Cr18Ni9 alloy) by plane milling insert and milling insert with complex groove that invented by ourselves has been done, meanwhile, the falling process of sticking-welding chip when milling insert cut-in and cut-out has been observed by high-speed photograph. Mechanical-thermal coupled field has been analyzed using ANSYS, and equivalent complex stress of the coupled field is larger than the stress of single field distinctly, it shows that they have a relation of direct proportion. The results of test and analysis show that the main reasons of adhesion failure are heat that produced in cutting process and the change of temperature grads during cut-in or cut-out and alternate tension stress and stress impact during cut-in or cut-out., which provides technical support and experimental data for the groove's optimization and reconstruction of milling insert with 3D complex groove.
