Corresponding author: Alexandru Epureanu Domneasca Street 47, Galati 800008 Romania, email: ADIABATIC PLASTIC DEFORMATION - THE case OF CUTTING PROCESS C. Maier, V. Vacarus , M. Banu, A. Epureanu Department of Manufacturing Science and Engineering, Dunarea de Jos University of Galati Romania ABSTRACT: Numerical and experimental research program was developed taking into account the high speed machining particularities. The results was analyzed by approaching the cutting process as ADIABATIC PLASTIC DEFORMATION process. Firstly, the process of material detaching was identified as thermodynamic transformation, and the tool rake surface and virtual finished surface was considered as the limit of the thermodynamic system in which this transformation took place. The ADIABATIC cutting process was defined as the cutting process in which: i) hole the mechanical work of the cutting force can be find as internal energy variation of the detached material, ii) hole the detached material can be find in the chips resulted and iii) the superficial layer doesn t support any irreversible transformations during the cutting process.
