Manufacturing industry is under increasing pressure of global competition, stricter environmental legislation and supply-chain demand for improved sustainability performance. The latter can be achieved through changes in products, processes, and systems. In this work, sustainability in machining processes is under the scope. Two sustainable alternatives are evaluated: cryogenic machining and high pressure assisted machining in comparison to conventional machining. The sustainability performance measures refer to environmental impact, energy consumption, safety, personal health, waste management and costs. The sustainability evaluation is supported with machining experiments on high-temperature Ni-alloy (Inconel 718). It is shown that sustainable machining alternatives offer a cost-effective route to improve the economic, environmental and social performance in comparison to conventional machining.
B.03 Paper at an international scientific conference
COBISS.SI-ID: 10974235In the thesis sustainability in machining processes is under the scope. This dissertation disseminates work related to sustainable cryogenic machining that has a high potential to cut production costs, raise the performances, and improve competitiveness by reducing resource consumption and creating less waste. The details about cryogenic fluids and their use in machining processes as an alternative to oilbased emulsions are presented.
D.09 Tutoring for postgraduate students
COBISS.SI-ID: 11380763In september 2011 it has been organized international conference MIT&SLIM 2011 in so organization of our research group (prof. J. Kopac) with Turkish project partner Sulyman Demirel University (prof. O. Colak).
B.01 Organiser of a scientific meeting
COBISS.SI-ID: 257664512First scientific research book from the field of sustainability in manufacturing processes, focused on innovative cryogenic machining process. Works explains and shows how and why machining performance can be increase by application of cryogenic fluid to the cutting zone. While cryogenic machining is not a new process, its benefits have not been fully exploited by industry. One reason for this is very few source information that explain what it is, how it works and why it works. And the second reason lies in placing importance of economics over environment and health. Overall, the book is pointing out that the cryogenic machining technology has a high potential to overcome position of problematic conventional machining processes, fulfilling all the sustainability pillars.
F.09 Development of a new technological process or technology
COBISS.SI-ID: 261082624Developed and patented has been delivery of liquid phase cryogenic liquid to the cutting zone. Additionally, this is provided with developed special active phase separator that separate gas from liquid phase. The liquid phase is then used for the delivery to the cutting zone, while gas phase is used as insulation and provider of inert atmosphere. Patent is interesting for industry and available on web.
