Optimization of multi-tool machining process

Abstract

Optimization of the machining modes for machine tools by criterion of the maximum productivity rate is complex and in many cases an unresolved problem. Increasing of machining modes leads to change the productivity rate. In the case of multi-tool machining processes, when cutters are engaged simultaneously or sequentially to define the optimal machining mode that gives the maximum productivity rate is an important problem. The present paper formulates a mathematical model based on maximum productivity rate by criterion for optimization of machining mode on machine tools. This case study represents a new mathematical model of the productivity rate of machine tools for multi-cutting processes with changes in machining modes. Practical application of new equations of the productivity rate for a machine tool with changes in the machining mode for the optimal multi-cutting operations is presented.
