Abstract: To reduce carbon dioxide emission of machinery manufacturing industry,the carbon emission resource of mechanical process was analyzed,and carbon emission function of machinery manufacturing was built.The carbon emission functions of typical mechanical process such as turning,sand mold casting,CO2 gas shielded welding and free forging were listed.The material carbon,energy carbon and craft carbon function description of typical mechanical process were realized to identify and evaluate the various carbon emission.The examples were used to research the carbon emission application,and the result showed that the machinery manufacturing carbon emission could be reduced effectively through process selection and process scheduling.

Key words: manufacturing process, typical mechanical process, carbon emission functions, process selection, process scheduling
