The theoretical waveforms and peaks of cutting force considering the force-deflection interactions were consistent with the experimental results. The deflection of slender ball-end milling cutter significantly reduces the cutting force, and the Pearson's correlation coefficient between the difference in the peak cutting force and maximum deflection in radial is larger than that of in feed directions. An analysis of the machining error of a cylindrical surface revealed that the deflection of slender ball-end milling cutter had a considerable effect on the machining error, and the compensation of slender cutter deflection effectively reduced the amplitude and fluctuation of the machining error.

Among the many physical quantities simulated by CPS, the cutting force is one of the most important quantities to be simulated. Until now, two fundamental challenges in achieving a functional and virtual machining process simulation system remain-the identification of cutter workpiece engagement (CWE) along a tool path and the development of computationally efficient simulation algorithms. The major bottleneck is the prerequisite requirement to calculate the complex CWE area before calculating the instantaneous cutting force. In this research, we propose an innovative solution to this problem. Using graphics processing unit's (GPU) parallel computing on the direct computation of the instantaneous cutting force (without calculating CWE), the cutting force computation, together with NC simulation, can reach up to 48 fps on a local PC, reaching the goal of CPS and digital twin simulation requirements in real time.}, keywords = {CPS; digital twin; 0; Industry 4; NC simulation; Instantaneous cutting force}, year = {2022}, eissn = {1433-3015}, pages = {6967-6978} } @article{MTMT:31689470, title = {Fast Dexelization of Polyhedral Models Using Ray-Tracing Cores of GPU}, url = {https://m2.mtmt.hu/api/publication/31689470}, author = {Inui, Masatomo and Kaba, Kohei and Umezu, Nobuyuki}, doi = {10.14733/cadaps.2021.786-798}, journal-iso = {COMPUT-AIDED DES APPL}, journal = {COMPUTER-AIDED DESIGN AND APPLICATIONS}, volume = {18}, unique-id = {31689470}, issn = {1686-4360}, year = {2021}, pages = {786-798}, orcid-numbers = {Inui, Masatomo/0000-0002-1496-7680; Kaba, Kohei/0000-0002-7580-4682; Umezu, Nobuyuki/0000-0002-7873-7833} } @CONFERENCE{MTMT:30649961, title = {Discrete Cutter-Workpiece Engagement for Five-Axis Milling Using Tri-Dexel Model}, url = {https://m2.mtmt.hu/api/publication/30649961}, author = {J.M., Theegarten and D., Plakhotnik and Z.M., Kilic and M., Stautner and E., Berckmann and Y., Murtezaoglu}, booktitle = {Proceedings of the 8th International Conference on Virtual Machining Process Technology (VMPT)}, unique-id = {30649961}, year = {2019}, pages = {1-6} } @CONFERENCE{MTMT:34590420, title = {Cutting Force Prediction in Robotic Machining}, url = {https://m2.mtmt.hu/api/publication/34590420}, author = {Riviere-Lorphevre, Edouard and Huynh, Hoai Nam and Ducobu, Francois and Verlinden, Olivier}, booktitle = {17th CIRP Conference on Modelling of Machining Operations, CIRP CMMO}, doi = {10.1016/j.procir.2019.04.143}, unique-id = {34590420}, abstract = {Modelling of cutting forces in milling is a key aspect for an accurate simulation of the process.

For this purpose, machine simulations are used to allow a preliminary characterization of the given process, thus minimizing the number of physical prototypes and scrap parts. However, these simulations are either extremely specialized for single problems, e.g., dynamic machine behavior, or they are simplified to a kinematic simulation of the machine without considering the machine behavior at all. This article presents a new approach for a real-time machine simulation by combining four types of simulations to close this gap. This proposed approach uses a voxel-based material removal inside a kinematic machine simulation as input parameters for a cutting force calculation. Afterwards, the forces are applied to a multi-body simulation of the static machine behavior. Starting point of the simulation is a hardware-in-the-loop coupling of a real CNC and a real-time visualization of a virtual machine tool. The simulation is experimental verified by comparing the simulated cutting forces and displacements with the measured forces during the process and the resulting shape of the manufactured work piece. The presented conclusions show the general applicability of the proposed method for the simulation of milling processes.}, keywords = {Material removal; Machine tool; Machine simulation; Cutting force calculation}, year = {2019}, eissn = {1433-3015}, pages = {2321-2328} } @article{MTMT:27228395, title = {Prediction of ball end milling forces based on special turning experiment data}, url = {https://m2.mtmt.hu/api/publication/27228395}, author = {Huang, Weijian and Li, Xi and Zhang, Yanfen and Liang, Guangdong and Gao, Weiwei}, doi = {10.1007/s00170-018-1919-8}, journal-iso = {INT J ADV MANUFACT TECHNOL}, journal = {INTERNATIONAL JOURNAL OF ADVANCED MANUFACTURING TECHNOLOGY}, volume = {96}, unique-id = {27228395}, issn = {0268-3768}, year = {2018}, eissn = {1433-3015}, pages = {4423-4430} } @inproceedings{MTMT:27074337, title = {On the Approach to CNC Machining Simulation Improving}, url = {https://m2.mtmt.hu/api/publication/27074337}, author = {Kats, E.

To estimate the amount of machining errors on the machined surfaces, the shape of the machined part should be derived. In computer simulation, a shape of a machined part is derived as a difference set between a workpiece and tool swept volumes. Hence, in this study, the generating method for tool swept volumes under effects of machine tool error characteristics has been proposed based on the tangency condition. In the previously proposed method, it was assumed that there was only one swept state, that is, two curves on a tool that generate tool swept volumes. However, there are other swept states of a tool, for example, two lines and a circle that generate tool swept volumes, and tool swept volumes of such states cannot be derived by the previously proposed method. Hence, in this paper, swept states of the generalized tool are classified as tool swept types based on the analysis of the tangency condition. Furthermore, the generating method of tool swept volumes for each tool swept type is proposed.}, keywords = {Machining error; Automation & Control Systems; Machine tool; Tangency condition; Tool swept volume}, year = {2016}, pages = {303-310} } @book{MTMT:30616367, title = {Detecting collisions in a simulated machining of a workpiece represented by dexels}, url = {https://m2.mtmt.hu/api/publication/30616367}, author = {Nicolas, Montana and Romain, Nosenzo}, unique-id = {30616367}, year = {2016} } @article{MTMT:25534430, title = {Development Status and Trend of CNC Machining Simulation Technology}, url = {https://m2.mtmt.hu/api/publication/25534430}, author = {REN, Jinggang}, doi = {10.16080/j.issn1671-833x.2016.05.062}, journal-iso = {AERONAUT MANUFACT TECH}, journal = {AERONAUTICAL MANUFACTURING TECHNOLOGY}, volume = {500}, unique-id = {25534430}, issn = {1671-833X}, year = {2016}, pages = {62-66} } @CONFERENCE{MTMT:26147354, title = {Tool swept volume generation for multi-axis machining with geometric errors based on the tangency condition}, url = {https://m2.mtmt.hu/api/publication/26147354}, author = {ARAI, Wataru and TANAKA, Fumiki and ONOSATO, Masahiko}, booktitle = {Proceedings of International Conference on Leading Edge Manufacturing in 21st century}, unique-id = {26147354}, year = {2015} } @article{MTMT:2996720, title = {Examination of the Machinability of Eutectic Aluminium Alloys}, url = {https://m2.mtmt.hu/api/publication/2996720}, author = {Horváth, Richárd and Mátyási, Gyula and Horváthné Drégelyi-Kiss, Ágota}, doi = {10.21062/UJEP/X.2015/A/1213-2489/MT/15/5/830}, journal-iso = {MANUFAC TECHN}, journal = {MANUFACTURING TECHNOLOGY}, volume = {15}, unique-id = {2996720}, issn = {1213-2489}, year = {2015}, pages = {830-836}, orcid-numbers = {Horváthné Drégelyi-Kiss, Ágota/0000-0002-1622-0820} } @article{MTMT:2899382, title = {The examination of surface roughness parameters in the fine turning of hypereutectic aluminium alloys}, url = {https://m2.mtmt.hu/api/publication/2899382}, author = {Horváth, Richárd and Horváthné Drégelyi-Kiss, Ágota and Mátyási, Gyula}, journal-iso = {U.P.B.
