Abstract

Abstract:

In order to correctly analyze the effect of enhanced cooling of the cutting media in the metal-cutting process, the orthogonal cutting process of aeronautical Ti6Al4V alloy in the enhanced cooling condition is simulated using a commercial finite element software Deform-2D, and the formation processof the serrated Ti6Al4V chips is simulated by geometric modeling, meshing, boundary condition setting and materialmodeling, etc. The chip for-mation, cutting force and cutting temperature in different enhanced cooling conditions are then analyzed and dis-cussed. The results indicate that, with the increase in heat exchange coefficient, the mean rake temperature de-creases, while the maximum cutting temperature and the cutting force change little.
