  • ABSTRACT: The paper presents the results of a multiobjective optimization of the elastic abrasive cutting process conditions of rotating workpieces made of C45 steel. A generalized utility function has been chosen as an optimization parameter and has been used as a complex indicator of the technological, economic and dynamic elastic abrasive cutting process parameters. For its determination an adequate theoretical and experimental model has been built, reflecting the complex influence of the elastic abrasive cutting conditions. The solution of the optimization problem has been reduced to the determination of combinations of values of the compression force, the cut-off wheel diameter and the workpiece rotational frequency for which the generalized utility function has a maximum and which guarantee an optimum combination of the following: the cut-off wheel lifetime, the tangential cutting force magnitude, the temperature of the cut piece and the cut - off operation cost and production rate.
