Abstract:

In recent years, the increase in energy demand and carbon emission constraints have forced industry sector to improve the process efficiency with respect to environmental sustainability. Therefore, resource saving has become not only an added value, but a real priority for manufacturing in the Industry 4.0 era. Life-Cycle Assessment (LCA) is a common practice for estimating the environmental impact of products during their life-cycle, and can be used more widely and easily if specific models focusing on each life-cycle phase are available. In this thesis, the manufacturing phase of machined pr

Abstract:

Titanium and its alloy (Ti-6Al-4V) are widely used in aerospace industries because of their light weight, high specific strength, and corrosion resistance. This study conducted a comparative experimental analysis of the machinability of Ti-6Al-4V for conventional flood coolant machining and sustainable dry machining. The effect of cutting speed, feed rate, and depth of cut on machining performance has been evaluated for both conditions. The machining time and surface roughness were found to be lower in dry machining compared to flood coolant machining. The tool wear was found to be unpredictab

Abstract:

In the last two decades, energy is becoming one of the main issues in the manufacturing industry as it contributes substantially to production cost, CO2 emissions, and other destructive environmental impact. Due to rising energy costs, environmental concerns and stringent regulations, manufacturing is increasingly driven towards sustainable manufacturing which needs to address the associated environmental, social and economic aspects simultaneously. One common approach is to achieve sustainability and to implement energy-resource efficient production management systems that enable optimisation

Abstract:

The competitive and ever growing business of aerospace technology is constantly pushing for improvements in the engine efficiency to deliver high performance with lower costs and reduced environmental impact. Over the past 50 years, the Turbine Entry Temperature (TET) has been increased by more than 400˚C to deliver improved engine performance. This has mainly been made possible with the advancement of materials and manufacturing technologies alongside improvements in computational capabilities. With the temperature capabilities of new materials ever expanding to meet efficiency targets, use o

Abstract:

The development of a sustainable manufacturing process requires a comprehensive evaluation method and fundamental understanding of the processes. Coolant application is a critical sustainability concern in the widely used machining process. Cryogenic machining is considered a candidate for sustainable coolant application. However, the lack of comprehensive evaluation methods leaves significant uncertainties about the overall sustainability performance of cryogenic machining. Also, the lack of practical application guidelines based on scientific understanding of the heat transfer mechanism in c

Abstract:

The use of cutting fluids in machining process is very essential for achieving desired machining performance. Due to the strict environmental protection laws now in effect, there is a wide-scale evaluation of the use of cutting fluids in machining. Consequently, minimal quantity lubrication (MQL), which uses very small quantity of cutting fluids and still offers the same functionality as flood cooling, can be considered as an alternative solution. This thesis presents an experimental study of face milling of automotive aluminum alloy A380 under four different lubrication/cooling conditions: dr

Abstract:

Sustainability is one of the challenges in today’s world. With limited resources at hand and hazardous impact of manufacturing processes on the environment, there is an increasing need for sustainable manufacturing. Sustainability actually has a broad meaning and is an all-inclusive concept. In this thesis what we are more interested in and focus on, are energy consumption and environmental impacts. Using system dynamics modeling and simulation, we can more easily understand the behavior of processes. Our selected processes are turning, milling and drilling operations in crankshaft machining a

Abstract:

<p>Process planning as a function for competitiveness is often neglected. However, as an intermediary between product development and manufacturing, it holds a key function in transforming product specifications and requirements into a producible process plan. Demands and requirements should be met concurrently as manufacturing costs and lead times are minimised. The focus of this thesis is the act of process planning, where the use of better methodologies, computer-aids and performance measurements are essential parts. Since process planning has the function of transforming demands and requir

As empresas não mais podem pensar em desenvolvimento econômico sem a paralela preservação do meio-ambiente e do benefício mútuo da sociedade. É importante que as condições econômicas e sociais sejam melhoradas ao longo do tempo, sem exceder a capacidade de suporte do planeta. As indústrias podem contribuir para melhorar esse cenário aplicando uma gestão sustentável de manufatura, uma vez que estes são um dos principais agentes causadores de impactos. No entanto, para que consigam aprimorar a sustentabilidade de seus processos, é indispensável, antes de tudo, conhecer o seu real desempenho. O

Abstract:

A simple model that includes energy and carbon dioxide (CO2) emissions in the economics of machining is proposed, which has been published in the highly respected and cited journal, Annals of CIRP (International Academy for Production Engineering). This is a timely analysis in current government discussions on a proposed carbon tax or a carbon cap and trade regime and greater energy efficiency. The new cost model is based on life cycle analysis methodology for the initial part production. An illustrative example is given showing that the cheapest electrical grid should not be chosen, if it al

L’avvento del paradigma dell’Industria 4.0 ha stravolto il settore industriale italiano e mondiale. Grazie ad esso si sta rivolgendo una crescente attenzione all’innovazione, digitalizzazione e sostenibilità dei processi produttivi. Il concetto stesso di produzione industriale si sta pian piano modificando radicalmente, tanto da denominare questo periodo la “quarta rivoluzione industriale”. Uno dei sette pilastri fondanti del paradigma della Industria 4.0 è l’Additive Manufacturing (AM). All'interno di questo ecosistema, l'AM gioca un ruolo chiave per lo sviluppo e la produzione di prototipi
