Optimization control method for carbon footprint of machining process

Energy conservation has become one of the key elements of core competitiveness for manufacturing enterprise. On the basis of studying the characteristics of carbon emissions in machining process, the state space model of carbon footprint for machining process is constructed, and carbon footprint transfer matrix is derived. It reveals the mechanism of generation, transmission, and coupling for carbon footprint in machining process. Considering the machining precision constraints and time constraints, the paper researched on optimization control method for carbon footprint of machining process based on dynamic programming to minimize the carbon emissions. Finally, this method is applied in a fracture splitting workshop, and the result shows this method can reduce 10.28% of carbon emissions in machining process. This paper provides theoretical and technical support for energy saving in machining process.
