This paper promotes sustainable production via an improvement of machining technologies through an alternative cryogenic machining process. Presented are comparative experimental results of cryogenic machining performances in accordance with conventional processes, through the analysis of: cutting forces, tool-wear, temperatures and costs.

COBISS.SI-ID: 11483163As cryogenic machining presents a sustainable alternative to conventional machining processes, in this work cryogenic machining and the influence of cooling/lubrication conditions on the surface integrity generated during turning of Inconel 718 are presented. The results show that the cryogenic machining process generates larger compressive residual stresses, and prevail at deeper levels beneath the machined surface.

COBISS.SI-ID: 11664411In 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 oil-based emulsions are presented.

COBISS.SI-ID: 11380763In this work, its influence on process dynamics is analyzed. Instability of machining and related onset of chatter is one of the major problem causing poor surface quality and reduced productivity. Therefore, chatter detection in machining process, based on course grained entropy (CER), is performed. While the cutting process has three directions of chatter occurrence, machining process coupling dynamics is characterized. Results show that for chatter detection, all three process dynamics directions have to be followed.

COBISS.SI-ID: 11447067High performance products used for special purposes in medicine and aviation are often manufactured from advanced materials such as titanium and nickel based alloys. As the most promising and effective technology for such production and repair the Laser Rapid Prototyping technologies are being used and implemented into the practice. Special focus has been orientated into the Laser Net Shape (LENS) technology where LENS is being applied in manufacture of modern medical implants such as bone fixation plate and effective repair of jet engine turbine inconel blades.
