The recent crisis of environmental pollution and resource depletion has become a major global issue, resulting in an increasing interest in remanufacturing in many countries. However, manufacturing for environmental protection is considered an additional cost factor by most companies. Therefore, governments worldwide have actively implemented remanufacturing policies to encourage the participation of numerous companies in the remanufacturing industry. As an eco-friendly technology, remanufacturing has impacted the environmental improvement and resource savings by reducing raw materials and production processes. In particular, the effect of machine tool and automobile part remanufacturing is very remarkable, since most parts are reusable. In this study, the standardization technology for remanufacturing process of machine tools is developed by remanufacturing of used vertical machining center. Based on the work operation sheet for establishing the process, the remanufacturing process chart and program were developed. The performance evaluation of machining centers before and after remanufacturing was also executed, to check the performance improvement of the remanufactured product. The performance evaluation criteria were established to improve reliability.
