Abstract: Manufacturing process is a main phase inducing resource
consumption and environmental pollution during the part life cycle.
Because of the variety of processes and complexity of their
environmental impact mechanism, there is still lack of an efficient
method to evaluate the environmental impact of part manufacturing
processes. Each process is regarded as an input-process-output unit
process, and can be described with process IPO model. Based on process
IPO models and L. B. Leopold interactive matrix, a new evaluation method
and its technical framework are presented. A case study of gear
manufacturing is discussed, which shows that the method is practical.
