Optimization of the processing mode of machine tools by using the criterion of minimum cost

Abstract

Calculation of the cost and optimization of the operating modes for automatic machine tools today is complex, and in many cases, an unresolved problem. Most equations for calculating the optimal machining processes with the changes in operating modes consider the change of machining mode by using the maximum productivity rate These equations do not reflect changes in the cost due to the changes in the failure of cutters with the change in operating mode. In manufacturing areas, it is necessary to have mathematical dependency of the cost of machine tools on the function of change in machining modes. In some cases of marketing environments, the minimum cost is more preferable than the maximum productivity of the machining process. The present paper has discovered a new analytical dependency of the cost for automatic machine tools that includes the changes in the failure of cutters with the change in operating modes.
