By studying the mean directional factor and its harmonics, the superior stability of the up-milling strategy over down-milling for both Hopf and flip chatter is demonstrated. The optimal engagement for a theoretical infinite stable depth of cut Hopf is obtained, as well as the expressions for the critical depth of cut. For flip chatter, three different cutting zones with different lobe shapes can occur depending on the radial engagement. It is also shown that while flip chatter cannot be completely eliminated by tuning the radial engagement alone, an engagement can be found in up-milling that maximises stability. Finally, the findings are validated through experimental tests. © 2024 The Author(s)}, keywords = {STABILITY; Optimisation; Milling (machining); CHATTER; CHATTER; Depth of cut; Milling; Milling; Optimisations; CHATTER STABILITY; Thin walled structures; Thin-walled parts; Milling stability; Milling strategies; Up millings; Feed direction}, year = {2024}, eissn = {1755-5817}, pages = {111-127}, orcid-numbers = {Dombóvári, Zoltán/0000-0003-2591-3220} } @article{MTMT:34486405, title = {The Effects of Delay on the HKB Model of Human Motor Coordination}, url = {https://m2.mtmt.hu/api/publication/34486405}, author = {Allen, Lara I. and Molnár, Tamás Gábor and Dombóvári, Zoltán and Hogan, S.

The vehicle dynamics are represented using a kinematic bicycle model, and a hierarchical lane-keeping controller is introduced with multiple delays in the feedback loop. An extension of the semidiscretization method is presented, in order to perform the stability analysis of the digitally controlled vehicle with multiple discrete time delays. The differences between the continuous approximation and the exact consideration of discrete time delays are highlighted. We show that in certain cases, neglecting the effects of quantization can lead to significant inaccuracies, especially when tuning the lower-level controller. The results are verified using a series of small-scale laboratory experiments.}, year = {2024}, eissn = {1741-2986}, pages = {330-341}, orcid-numbers = {Bártfai, András/0000-0002-3205-9125; Takács, Dénes/0000-0003-1226-8613} } @inproceedings{MTMT:34504863, title = {High-density stability map – stability identification in milling by stop-and-go tool motion}, url = {https://m2.mtmt.hu/api/publication/34504863}, author = {Kiss, Ádám and Bachrathy, Dániel}, booktitle = {Book of Abstracts. 39th Danubia-Adria Symposium on Advances in Experimental Mechanics. 2023 Hungary}, unique-id = {34504863}, year = {2023}, pages = {1}, orcid-numbers = {Kiss, Ádám/0000-0002-7074-4553; Bachrathy, Dániel/0000-0003-1491-1852} } @CONFERENCE{MTMT:34472991, title = {Időben változó paraméterű esztergálás véges idejű stabilitás vizsgálatának numerikus szimulációs problémája}, url = {https://m2.mtmt.hu/api/publication/34472991}, author = {Bártfai, András and Dombóvári, Zoltán}, booktitle = {XIV.
