“…Dahmus et al [7] studied, with a global approach, the environmental impact of the manufacturing process (such as turning, milling, etc) taking into account electric consumption but they have also studied the environmental impact of lubricant use and lubricant removal. In the same way, to reduce the use of lubricants, several works have been made such as High Pressure Jet Assisted Machining or Cryo machining [8], [9]. Some studies have also been conducted in order to evaluate the electric consumption of machining from CNC program of the part to manufacture.…”

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.

Prijedlog načela i tehničke smjernice za proizvođače alata po mjeri, strojeva i specijalne opreme FRAMEWORK PROPOSITION AND TECHNICAL GUIDELINES FOR MANUFACTURERS OF CUSTOM MADE TOOLS, MACHINERY AND SPECIAL EQUIPMENTMatic Tepeš, Peter Krajnik, Janez KopačOriginal scientific paper This paper overviews the state-of-the-art in modern forms of organization, collaboration and flexibility, trends and forecasts of the automotive industry as a representative buyer of tools, machines and special equipment, as well as life cycle management, sustainability and possibility for added value creation in these industry sectors. Based on this, a framework called "smart tool, machine, and special equipment" is proposed. A part of the research done on Slovene manufacturers is presented, where the technological indicators important in the implementation of the proposed framework are identified and ranked regarding to their importance. Additional suggestions by the manufacturers are also provided, as well as critical analysis and discussion of the findings.

Na temelju toga predlaže se okvirno načelo nazvano "pametni alat, stroj i specijalna oprema". Daje se dio istraživanja provedenog na slovenskim proizvođačima kod kojih su prepoznati tehnološki indikatori važni za implementaciju predloženog načela, te su rangirani u skladu s njihovom važnosti. Daju se i dodatne primjedbe koje su stavili proizvođači, te kritička analiza i rasprava rezultata. Ključne

“…Other works have been made for reducing the lubricants consumption by minimal quantity lubrication method, high pressure jet-assisted machining or cryogenic machining. Some other studies developed methodologies for ecological impact assessment of TM processes [5][6][7][8]. Additive Manufacturing (AM) is a relative young technology that has the potential to fabricate geometrically complex customized products (functional parts and tooling) using less material and producing less waste.…”

Abstract. Additive Manufacturing (AM) technologies allow developing and manufacturing very complex shaped parts and functional products with a high level of customization, being a great alternative to Traditional Manufacturing (TM) methods like injection molding, die-casting or machining. Due to the importance of cleaner production in the field of manufacturing processes, sustainability of AM processes needs to be assessed in order to make easier its acceptance and implementation in the industry. Furthermore, the manufacturers can improve their competitiveness and profitability by considering the ecological aspects during the manufacturing step of a product. This paper gives a survey on sustainability issues related to AM.
