The abrasive flow machining (AFM) represents a very efficient sustainable polishing process. Basically, the AFM is suitable for finishing of both external as well as internal surfaces. However, the efficiency of the AFM process depends on a number of factors, which can be classified in three groups, namely, the polishing media factors, the AFM machine factors and the workpiece factors. One of the major problems in the AFM process is to determine the relationship between these factors and the process results, i.e., the workpiece surface roughness or the changes in geometry of workpiece.
B.03 Paper at an international scientific conference
COBISS.SI-ID: 11483931In 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 Ni-alloy (Inconel 718). It is shown that alternatives offer a cost-effective route to improve the economic, environmental and social performance.
B.03 Paper at an international scientific conference
COBISS.SI-ID: 10974235The paper presents methods for achieving production sustainability on a machining technology level. In order to tackle the sustainability issues, the paper promotes sustainable production via the improvement of machining technologies that have a high potential to cut costs and improve competitiveness by reducing resource consumption and thus creating less waste. The idea is confirmed by a case study on the implementation and sustainability evaluation of innovative cryogenic and high pressure jet assisted machining processes in comparison to conventional machining process.
F.18 Transfer of new know-how to direct users (seminars, fora, conferences)
COBISS.SI-ID: 11063323Nowadays, hand polishing is not the most appropriate process for finishing of complex shape workpieces, because of ensuring adequate quality and long processing time. In addition, certain shape of workpieces (various holes and closed shape) cannot be finished with manual polishing. Therefore, different machine polishing processes are developed and enable finishing in all fields. The machine polishing significantly reduces the polishing time and the control of process ensures adequate quality, but these finishing processes are quite recent.
