Abstract:
The present paper discusses mathematical modelling with regard to deformation processes resulting from chip forming and removal when cutting heavilyprocessed materials in a condition of non-homogeneous stress state, which can evoke undesirable self-excited oscillation. By describing the chip forming and removal process a synthesized rheological model was used.
Key words:
cutting materials, elastic and plastic deformation, relaxation, rheological model
