Pursuing the green manufacturing(GM) of products is very beneficial in the alleviation of environment burdens. In order to reap such benefits, green manufacturing is involved in every aspect of manufacturing processes. During the machining process, cutting fluid is one of the main roots of environmental pollution. And how to make an optimal selection for cutting fluid for GM is an important path to reduce the environmental pollution which incurred by application of cutting fluid. The objective factors of decision-making problems in the traditional selection of cutting fluid are usually two: quality and cost. But from the viewpoint of GM, environmental impact(E) should be considered together. In this paper, a multi-object decision-making model of cutting fluid selection for GM is put forward, in which the objects of Quality (Q), Cost(C) and Environmental impact (E) are considered together. In this model, E means to minimize the environmental impact, Q means to maximize the quality and C means to minimize the cost. Each objective is analyzed in detail too. A case study on a decision-making problem of cutting fluid selection in a gear hobbing process is analyzed, and the result shows the model is practical.

绿色制造是人类社会可持续发展战略在现代制造业中的体现。绿色制造的研究和实施需要理论体系的支持。本文在介绍可持续发展战略的理论内涵的基础上，结合绿色制造的特点和相关研究，建立了绿色制造理论体系的初步框架。

In order to provide an effective approach to assisting decision makers to choose between realistic alternatives on the shop floor for Green Manufacturing, a decision-making framework model of machining process planning for Green Manufacturing is established from three aspects, including decision-making problem set, decision-making objectives and their mapping relationship. The considerations in traditional decision-making of machining process planning are quality, time and cost. But from the point of Green Manufacturing, the factors of resource consumption and environmental impact are considered also in this model. A new algorithm integrating Grey Relation Analysis and Analytic Hierarchy Process is proposed to aid the process of decision making, especially for the handling of the relativities of the objectives. A case study of the selection of machine tools for Green Manufacturing is given with the data provided by the industry partner. It shows the feasibility and effectiveness of the model and method presented.

Noise reduction in the shop-floor is one of the important parts of green manufacturing. In the shop-floor, machine tool is one of the main noise sources. A new approach is discovered by investigation that remarkable noise reduction can be obtained by optimizing the scheduling of parts and machine tools. Based on the discovery, A new method of noise reduction is proposed in this paper. A noise reduction scheduling model in the shop-floor is established, and the application of the model is discussed also. A case is studied, which shows that the method and model are practical with 2.46db noise reduction.

With the development of CNC, communication and CIM technology, the connotation and functions of DNC have been greatly enlarged. In order to describe the features and development of contemporary DNC, a new concept, integrated DNC, is presented in this paper. The connotation of integrated DNC and other relative concepts are discussed. Four control architectures of integrated DNC are proposed, including bi-hierarchies, tri-hierarchies, quadri-hierarchies and acrossshops architectures. A case study of integrated DNC is introduced.
