The problem of global warming is getting worse,and countries all over the world are focusing on the problem of greenhouse effect,and it is urgent to develop the low-carbon concepts.The rapids development of my country's manufacturing industry has also had a greater impact on the environment,in which carbon emissions have increased significantly.As a major member of my country's manufacturing industry,grinding machines are imperative to reduce their carbon emissions.Based on relevant domestic and foreign carbon footprint research,a carbon footprint calculation model for the spindle sleeve grinding process is established.At the same time,the particle swarm algorithm is used for solving the optimal parameters to decrease the carbon emissions and processing costs in the process premeditating the processing cost factors,and a carbon footprint accounting system based on it is developed to achieve the goal of low-carbon manufacturing.First of all,according to the research status of low-carbon manufacturing at home and abroad,the exploration of low-carbon manufacturing should be conducted from the perspective of product life cycle.According to the current status of carbon emissions research in the manufacturing process at home and abroad,carbon emissions research is mainly to explore the carbon emissions of a specific part in a specific process.According to the status quo of research on optimization of machining process parameters at home and abroad,most of the researches on parameter optimization are based on multi-objectives,and there are few studies on carbon emissions from grinding.Based on the above-mentioned domestic and foreign current situation,the spindle sleeve is used as the research object to analyze the carbon emission system structure and characteristics in the whole life cycle.Based on it,it need to analyze the difficulty of each accounting boundary in the life cycle,delimit the grinding process as the accounting boundary,and explore the spindle sleeve Carbon emission calculation during grinding process.Secondly,on the basis of the grinding process as the accounting boundary,the energy and material consumption analysis of the grinding machine in the process is explored to determine the carbon emission source during the grinding process.Based on carbon emission sources,the impact of various factors on carbon emissions from grinder energy consumption,grinding tools,grinding fluids and other factors is explored,and a grinding carbon emission accounting model based on this is established,and then an example of enterprise production and processing spindle sleeves Investigate the carbon emissions produced by the cylindrical finish grinding under different grinding dosages,and analyze the accounting results.Comprehensively consider the processing cost factors of the grinding process,the processing cost and carbon emissions is optimized,and its optimization model in combination with the constraints is constructed.The unified objective function method and evolutionary algorithm are determined through comprehensive analysis of these to achieve the goal of low-carbon and low-cost combined with Matlab for mathematical modeling.Finally,based on the calculation model of the spindle sleeve grinding processing and its application,combined with the system requirements,a carbon footprint calculation system for the outer cylindrical finish grinding processing of the spindle sleeve is developed.The system is mainly based on accounting and optimization functions,quantifying the carbon emissions of fine grinding processing and optimizing its parameters for enterprise developers to facilitate analysis and decision-making,and to realize the energy-saving and emission-reduction goals of manufacturing enterprises.
