Energy consumption assessment of remanufacturing processes

Abstract

In order to analyze the energy consumption of the remanufacturing processes, the energy consumptions of electrical, fuel oil and auxiliary materials in remanufacturing process are conducted by considering as embodied energies. Energy assessment methods of typical processes of laser cladding and turning are established based on the thermodynamic theories and metal-cutting theories. For uncertainty of failure degree and processes, energy consumption methods about one remanufacturing process sequence are presented by using probability theory. The upper and the lower values of energy consumption are given, which can be used as a basic theory for developing energy assessment standards of remanufacturing technology.
