Tóm tắt

It is estimated that the industrial sector is responsible for 29% of the United States’ greenhouse gas emissions. Recent efforts have sought to reduce the carbon footprint of manufacturing activities. Research suggests that a key to further reducing industrial-based greenhouse gas emissions is to more accurately characterize the carbon footprint of manufacturing processes. Life cycle assessment is a powerful tool that can be utilized to characterize the life cycle environmental impacts of a process. Current life cycle inventory databases that are used in life cycle assessments only have limited coverage on manufacturing operations. This article develops a parameterized process model for computer numerical control grinding, which enables the calculation of life cycle inventory data in a relatively rapid fashion and has some substantial characteristics, such as transparency, engineering quality, and the ability to reflect changes when new information is secured. Surface grinding of cobalt–chromium alloy knee implants is used as a case study to demonstrate the approach.
