Features of Creation of Surface Layer Mechanical Condition Parameters in Orthogonal Cutting

In this article, the technique and research results on creation of surface layer mechanical conditions parameters at orthogonal cutting are presented. Stress tensor, strain rate tensor and general mechanical condition factors distribution along flow lines were obtained. Distributions of stresses, strain rates, mean normal stress and stress state index along flow lines consist of three steps of quasi -monotonous deformation. On every step there is a monotonous increasing or decreasing of these parameters. It is demonstrated that creation of surface layer mechanical condition parameters in metal cutting and surface plastic deformation methods follow common patterns. Experimental research results confirmed the validity of proposed analytical models for stressing programs in orthogonal metal cutting.
