<p>In this paper, a model for the optimization of the production energy of a machining process is developed considering the residues recycling. To minimize the production energy, the model considers the variation of energy with cutting parameters and the energy spent: in machine setup, in cutting itself, in tool change, on pumping the cutting fluid, on cutting fluid change, on completion of the emulsion, on recycling of the emulsion, on recycling of the metal chips, and on recycling of the cutting tool, and additionally the model considered the embodied energy of the cutting tool and the embodied energy of the cutting fluid. The model is evaluated with several examples using cutting data from literature, intentionally selected to compare the mineral and vegetable base oils to improve sustainability.

摘要

In this paper, a model for the optimization of the production energy of a machining process is developed considering the residues recycling. To minimize the production energy, the model considers the variation of energy with cutting parameters and the energy spent: in machine setup, in cutting itself, in tool change, on pumping the cutting fluid, on cutting fluid change, on completion of the emulsion, on recycling of the emulsion, on recycling of the metal chips, and on recycling of the cutting tool, and additionally the model considered the embodied energy of the cutting tool and the embodied energy of the cutting fluid. The model is evaluated with several examples using cutting data from literature, intentionally selected to compare the mineral and vegetable base oils to improve sustainability. The presented optimization model can be useful for industrial application to reduce the energy consumption and environmental impact.
