Abstract

In machining the selection of cutting parameters is done normally on the basis of the optimization of either cost or production rate or profit. But due to government policies the environmental aspects also become important. Major environmental impacts are due to electrical energy consumption in machine tool during machining. So it is essential to minimise energy consumption. This criteria of minimisation of energy should also be considered while selecting the cutting parameters along with the other criteria in view of the present day requirements to reduce pollution. In the present study a multiobjective mathematical model is presented for optimizing energy consumption, processing time and cost during a turning process. Experimental studies are used for validating the model. The optimization of experimental values and theoretical model is done using same range of parameters. Results are compared and discussed.
