Aims: Machine tool remanufacturing input material, energy and Co 2 emissions are assessed to help conclude feedbacks about environmental benefits and burdens, what is necessary to enable educational institutions to conduct remanufacturing of machine tools as a business to deliver closing the loop supply chain for sustainable manufacturing. Study Design: Bridgeport manual milling machine is remanufactured within insights of new ecodesign ideas to change it into CNC vertical milling machine where machine enabled to be flexible to embed cheap emerged CNC technology. Thus enough data can be acquired to be analyzed for feasibility study. Methodology: A step by step case study of CNC machines technology introduction into conventional machine architecture is illustrated. Modules of ball screws and ball linear guide ways Original Research Article

A comprehensive evaluation system of die quality, a multiplayer hierarchical amendment index system according to the characteristics of cold stamping die production, an evaluation standard referring to the technique and design rules of dies, and a scientific evaluation by using the multiplayer hierarchical and the fuzzy comprehensive evaluation methods are presented in this paper. The applications show that the system can be used to evaluate the die quality objectively, fairly, and reasonably.

Abstract. At present, Information System is facing a big challenge: How to effectively manage legacy management system (EMS, NMS), simultaneously ,also can manage new services which are joining at any moment. in this paper, we first analyze the technology background and architecture of JMX. then design and implement a JMX-based dynamic network sports management service model, which can effective and convenient for managing legacy system, but also can seamless add new service to the system. Thus, this system provide a perfect resolution for the challenge, it will have a good future for implementation.
