The rigid-plastic model of cutting problem is analyzed subject to a Coulomb-Mohr
yield condition. The fields of stress, of strain and of deformation are investigated. Local
continuation of stress field to rigid zones (the blank body and cuttings) is constructed. The
existence region of full solution is detected and selection criteria of preferred solution is done.
Depending of strain distribution and density changes in cuttings is given.
Keywords: cutting problem; rigid-plastic model; Coulomb-Mohr yield condition.
