The work concerns on the analysis of the influence of selected parameters of rolling process on state of surface layer. The numerical application in APDL language, in ANSYS/LS-Dyna system, for analysis of physical phenomena (strains) which occur in surface layer of material was developed. Physical phenomena, on a typical incremental step, were described in an updated Lagrange'a description, which shows the lowest sensitivity on large deformations. Carried out simulations for machining of various materials, which are characterized by a different plastic strain, allows to determine the factors influence on the shape of chip and wear of a turning tool which determine quality (surface roughness of the product). During the rolling process the influence of friction coefficient on the state of surface layer of processing material was investigated. The examples of numerical simulations results for selected time steps were presented.
