Investigation of energy, carbon dioxide emissions and costs in single point incremental forming

Abstract

The LCA of sheet metal forming processes is lacking in studies of sustainability issues and quantification of energy and carbon dioxide (CO2) emissions. This paper summarizes an investigation of the relationship between technical parameters in single point incremental forming (SPIF) and energy use. Using a life cycle analysis (LCA) approach, the associated CO2 emissions are estimated. Costs are calculated using an economic model presented in CIRP previously, and modified for SPIF. The relationships are used in an optimization example which entails producing a complex hat with reduced energy use and CO2.
