Abstract: Aiming at the gear hobbing machining process quantitative calculation problem,a gear hobbing process carbon emission quantitative calculation model and its optimization are proposed.The characteristics of material,energy consumption and carbon emissions in gear hobbing machining are analyzed,to share all kinds of carbon emissions with parts and parts processing time as the unit,complete a single gear quantitative calculation of carbon emissions.Considering the complete time and processing quality constraints,a multi-objective optimization model is established,which takes gear hobbing spindle speed and feed as the variables,the carbon emission and finished cost as the optimization objectives.Genetic Algorithm(GA) is designed to solve the optimization model,which has improved the carbon emission at the same time reduced the processing cost.A simulation experiment case is performed to verify the feasibility of the carbon emission quantitative calculation model optimization method.

Key words: hobbing process, quantitative calculation, genetic algorithm, carbon emission
