Numerical simulation of metal cutting using the software DEFORM 2D

Machining is one of the jobs that are widespread due to a number of advantages. The goal of each company, whose activity is associated with machining, is separation of particles in optimum working conditions. Optimum working conditions, minimal production costs and the tool wear can be reached due to experiments which are very expensive or determined with computer programs based on the finite element method. In this work the numerical simulation of orthogonal turning of AISI 1025 steel is made in the software DEFORM 2D. The goal of making the numerical simulation of machining is to define the conditions of processing with a minimum temperature of the cutting part of the tool. With regard to the Taguchi plan experiment, statistical analysis was carried out of the output data "the temperature of the cutting parts of the tool" by using analysis of variance. Based on the regression equation it was concluded what parameter has the biggest impact on the observed output value.
