Optimization of machine tools by using the maximum productivity rate

Abstract

Calculation of the productivity rate 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 minimum cost These equations do not reflect changes in the productivity rate 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 productivity rate of machine tools on the function of change in machining modes. In some cases of marketing environments, the maximum productivity rate is more preferable than the minimum cost of the machining process. The present paper has discovered a new analytical dependency of the productivity rate for automatic machine tools that includes the changes in the failure of cutters with the change in operating modes.
