“…For example, at the tool path planning level, given the specific operating characteristics of most modern computer numerically controlled (CNC) machine tools including construction (with stacked axes) and controller performance, there is usually a preferred orientation of a workpiece on the machine tool and, for that orientation, a preferred tool path to remove the desired material. 5 This can often result in substantial savings in energy to produce the same part feature with no loss of cycle time (Fig. 1).…”

The pressing needs of energy, water and other resource conservation worldwide is a major engineering challenge. In manufacturing, developing green technologies (from process and tooling to the entire enterprise) is one way to insure that future manufacturing systems are sustainable. To do this, innovation in advanced manufacturing is needed. The basic requirements of green technology are discussed along with methods and tools to insure they are effectively applied and their impacts measured. For situations in which the manufacturing environmental burden is less than the burden for the use of the product leveraging is proposed to insure a total life cycle impact reduction. Examples of several green technologies are presented.

Cleaner production and sustainability are of crucial importance in the field of manufacturing processes where great amounts of energy and materials are being consumed. Nowadays, additive manufacturing technologies such as Direct Additive Laser Manufacturing allow us to manufacture functional products with high added value. Insofar as environmental considerations become an important issue in our society, as well as legislation regarding environment become prominent (Normalization ISO 14 044), the environmental impact of those processes have to be evaluated in order to make easier its acceptance in the industrial world. Some studies have been conducted on electric consumption of machine tools (stand-by consumption, in process consumption, etc) but only a few studies take into account the whole existing environmental flows (material, fluids, electricity). This paper presents a new methodology where all flows consumed (material, fluids, electricity) are considered in the environmental impact assessment. This method coupled a global view required in a sustainable approach and an accurate evaluation of flows consumption in the machine. The methodology developed is based on a predictive model of flows consumption defined from the manufacturing path and CAD model of the part which will be produce. In order to get an accurate model of the process, each feature of the machine is modeled. The goal of this work is to integrate this model into the design loop for additive manufacturing parts.

“…Based on the tool paths from CNC codes (e.g., G-code), the energy consumption assessment for the spindle axis, feed axis and load/unload cycle were formulated (Avram and Xirouchakis, 2011). Based on an established energy consumption model from tool paths, a Web-based system was developed for environmental sustainability monitoring and evaluation (Kong et al, 2011). In the system, tool path generation strategies for different machining features were modeled in terms of energy consumption.…”
