Abstract
This paper is a development of the study of hardness of workpiece surface layer, case of C45 steel orthogonal cutting, as function of cutting regime parameters and forces and geometry of the cutting tool [1]. The size of the experimental data imposed an extended use of computer assisted statistical applications. The influence of cutting parameters and radius of the cutting tool on hartness was modeled with all variables and their interactions, seven factors, based on a multivariate regression function. The model with three factors was a sinthetic application for this dependence and we established that the mainly influence on hardness is due to the factor radius of tool, which explained reliability. The dependence of hardness from cutting forces, modeled with a bivariate copula, proved a strong dependence of the variable HV.
