A new approach to minimize carbon emission rate in turning processes

Abstract

Abstract This paper aims to analyze the correlation between CNC machine turning properties and the CO2 output, so that a minimum value is obtained and an optimal process is created. The need to find an optimal process is to help in reducing carbon emissions during the ongoing climate change. In this study, the total carbon emission values in turning have been investigated by calculating the carbon emission values of the features used in turning processes, which are work piece, cutting tool, machine electrical system, cutting tool features, cutting parameters, chip removal, etc. The actions to be taken in experimental study are decided. In the first stage, the equations required to calculate the carbon emission values are determined. Then, carbon emission values were calculated. An experimental design was created in the Taguchi method in order to use the carbon emission values obtained. In the experimental design, the cutting parameters were chosen as the factor, while the cutting time and carbon emission values were chosen as the response. Next, optimum conditions were determined in minimizing the carbon emission value. Later, the most effective cutting parameter with minimum carbon emission value was found in an analysis of variance. Unlike the studies on carbon emission in the machining sector in the literature, the effect of cutting parameters on cutting time and thus on carbon emission was also investigated. Again, in the study, unlike the studies in the literature, a numerical value is given in determining the lowest carbon emission.
