These alloys are, however, difficult to machine due to their high strength at elevated temperatures, low thermal conductivity and work hardening. In this study, micro milling of Inconel 600 super alloy has been carried out and the effects of the key input parameters (cutting speed, feed rate, depth of cut) on response parameters (burr formation, surface roughness and tool wear), under various cooling conditions (dry, wet and cryogenic), have been analyzed. High speed micro milling (range up to 80,000 RPM) was carried out, while keeping the feed rate values below and above the cutting edge radius. The Taguchi design of experiments was used during this study. The results have been analyzed using SEM and 3D optical microscopy. Analysis of Variance (ANOVA) revealed that the best surface roughness values can be achieved under cryogenic machining condition with an overall contribution ratio of 28.69%. It was also revealed that cryogenic cooling resulted in the highest tool life with the contribution ratio of cooling conditions at 26.52%.}, keywords = {Precision machining; green manufacturing; Micro-milling; Inconel 600; renewable & sustainable manufacturing}, year = {2023}, eissn = {2072-666X}, orcid-numbers = {Alruqi, Mansoor/0000-0002-0740-3967} } @article{MTMT:33061370, title = {Finite element simulation of micro-milling of hardened tool steel}, url = {https://m2.mtmt.hu/api/publication/33061370}, author = {Balázs, Barnabás Zoltán and Takács, Márton}, doi = {10.1088/1757-899X/1246/1/012019}, journal-iso = {IOP CONF SER MATER SCI ENG}, journal = {IOP CONFERENCE SERIES: MATERIALS SCIENCE AND ENGINEERING}, volume = {1246}, unique-id = {33061370}, issn = {1757-8981}, abstract = {The demand for miniature components has been growing steadily in recent years. One of the most important technologies to produce such small components is micro-milling. Although the technology is highly researched, there are still many difficulties due to the size reduction, which makes the finite element simulation, as well as the exploration of cutting process challenging. The aim of the research was to investigate the micro-milling process, especially those features, that can be measured very complicated due to the small sizes at the experiments, such as the cutting temperature, and stresses, by means of finite element simulation. The results show that the cutting temperatures are smaller than in the case of conventional size machining, moreover, the stresses do not show significant changes during the cutting edge impact. Finally, the results were validated by the experimental results through comparing cutting force components, which shows a good agreement.}, year = {2022}, eissn = {1757-899X}, orcid-numbers = {Balázs, Barnabás Zoltán/0000-0001-5235-1388; Takács, Márton/0000-0001-6882-1540} } @article{MTMT:32003411, title = {A fogásmélység hatása a mikroméretű forgácsleválasztás dinamikai sajátosságaira}, url = {https://m2.mtmt.hu/api/publication/32003411}, author = {Balázs, Barnabás Zoltán and Geier, Norbert and Poór, Dániel István and Pereszlai, Csongor and Takács, Márton}, doi = {10.47833/2021.1.ENG.007}, journal-iso = {GRADUS}, journal = {GRADUS}, volume = {8}, unique-id = {32003411}, year = {2021}, eissn = {2064-8014}, pages = {266-271}, orcid-numbers = {Balázs, Barnabás Zoltán/0000-0001-5235-1388; Geier, Norbert/0000-0001-7937-7246; Poór, Dániel István/0000-0002-8036-7966; Pereszlai, Csongor/0000-0002-2336-6457; Takács, Márton/0000-0001-6882-1540} } @article{MTMT:31793490, title = {A review on micro-milling: recent advances and future trends}, url = {https://m2.mtmt.hu/api/publication/31793490}, author = {Balázs, Barnabás Zoltán and Geier, Norbert and Takács, Márton and Davim, J.
