Simulation Research of Machining-Induced Surface Layer Operational Characteristics

The analysis of the rheological model, which formalizes the influence of the main technological factors on the formation of residual stresses and strains in the cutting process, is described in the article. An explanation of the physical phenomena of deformation processes during cutting and comparing theoretical conclusions with simulation studies results are given. The main task, the solution of which is proposed, is the generalization and system analysis of methodological studies of the influence of the technological factors and the cutting tool’s geometry on the formation of the stress-strain and thermodynamic state of the surfaces of the workpieces during the cutting. Such problem-oriented modeling results are the basis for predicting the impact of technological process parameters on the formation of product’s operational properties. An original scheme for determining the residual strains on top and in the machined surface depth is proposed. The analysis of the influence of technological operation data on residual strain formation was carried out using DEFORM 3D simulation.
