MODELING MANUFACTURING PROCESSES OF CUTTING

Daniela Carmen Koukach, Marcel Popa, Grigore Marian Pop, Dan Preja

Abstract


In the second part of the article about modeling manufacturing processes of cutting, is prezented a numerical 2D simulation for the modeling of orthogonal cutting processes  by using the commercial software SFTC DEFORM-2D ® V 9.1 for AISI 1045 steel (DIN 1.1191). At the same time it will be shown the experimental determinations for selecting an appropiate friction coefficient, that minimize errors in predicting the cutting force. For the chosen friction coefficient, it will be determined the maximal chip temperature with the help of the created model, whici will be compared with the experimental values presented in the literature. The researches have been conducted in an intership at the Institut for Machining Tool, University Stuttgart, Germany.
