Abstract: To judge the remanufacturability of implementing mechanical parts remanufacturing,the overall framework of remanufacturability evaluation for mechanical parts was proposed.The failure condition of mechanical parts was determined based on fuzzy evaluation.The quantification methods of remanufacturability evaluation indexes including technical feasibility,economic feasibility as well as resource and environment index were presented,and the model of remanufacturability evaluation for mechanical parts based on quantified failure features was established.The proposed model was illustrated in a case of worm gear remanufacturing,and the result showed the better remanufacturability of this worm gear.
