abstract

Self-excited and forced vibrations are important topics in machining processes because their occurrence results in poor surface finish, increase in tool wear and hampers productivity. In this paper, turning process is modeled as a SDOF dynamic system including quadratic and cubic structural nonlinearities. The effect of tool flank wear, as a contact force between the work-piece and tool, is addressed vigorously. Multiple scale method is used to find the solution of the nonlinear dynamic equation including regenerative chatter, forced excitation and tool wear. It is shown that, width of cut can be considered as the bifurcation parameter of the system. Primary, super-harmonic and sub-harmonic resonance situations are discussed. Specifically, under super-harmonic resonance, turning process shows interesting behavior. Finally, stability of the steady state motion is investigated in terms of tool wear length, width of cut and spindle rotational speed. Results are compared for two distinct cases: system with fresh and worn tools.
