Parameters Optimization of Turning Process under Extended Carbon Emissions Accounting Method

Abstract

Aims: To evaluate the environmental benefits of the manufacturing system and optimize the process parameters, a more effective method of evaluating environmental benefits should be adopted, which can be used for process parameters optimization. Background: Mechanical manufacturing systems generally include raw materials, energy, products, waste emissions, capital, labor, and other elements. The Extended Carbon-Emissions Accounting (ECEA) method is an extension of the traditional Carbon Emissions Accounting (CEA) method, which can account for capital and labor elements in equivalent carbon emissions similar to other elements. Methods: Through the ECEA method, the Extended Carbon Dioxide Emissions (Ex-CDE) of the manufacturing system are obtained by accumulating the value by multiplying the consumption of each element and its Extended Carbon Emission Factor (Ex-CEF), which can be used as the environmental benefits of the manufacturing system. Then, a comprehensive optimization case of lowcarbon, high-efficiency, and low-cost can be built, including all consumption elements, and the COMPLEX algorithm is used to solve this optimization problem. Results: Taking a turning process as an example, through the ECEA method combined with the COMPLEX algorithm, the process parameters for environmental benefits or comprehensive optimization can be solved. Conclusion: ECEA method is suitable for environmental benefits analysis and optimization of the manufacturing system.
