Among the benefits of feed rate scheduling, this paper focuses on controlling the tool load and optimizing the machining time. Although the advantages of feed rate scheduling are undeniable, some areas remain still to be addressed. In order to control the tool load, geometric methods are often used, which are based on keeping a specific parameter, such as chip thickness or material removal rate (MRR) constant. However, a high level of tool load control can only be provided if cutting force models or experimental-based techniques are used. Besides traditional methods, this paper presents an artificial neural network (ANN)-based feed rate scheduling method to keep the tool load constant, using data gained by preliminary cutting experiments. A case study demonstrates that a significantly higher level of tool load control can be achieved with this method as compared to the geometric models. Besides controlling the tool load, the present feed rate scheduling method also addresses the consideration of acceleration limits which is of great importance for practical uses. The application of feed rate scheduling in trochoidal milling is also discussed in detail in this paper. This area has not received enough attention, as due to the limited fluctuation of cutter engagement, the tool load was considered as well-controlled. However, experiments have shown that in the case of trochoidal milling, the introduction of feed rate scheduling can still further increase the machining efficiency. Using the developed ANN-based feed rate scheduling method, significant progress could be made as compared to conventional technologies in controlling the cutting force and optimizing the machining time. In the present case study, a reduction of 50% in machining time was achievable by adjusting the feed rate without increasing the peak value of cutting force.}, year = {2023}, eissn = {1433-3015}, pages = {487-506}, orcid-numbers = {Jacsó, Ádám/0000-0001-8247-2332; Szalay, Tibor/0000-0003-3446-2898} } @inproceedings{MTMT:33103738, title = {S-Shape Feedrate Scheduling Method with Smoothly-Limited Jerk in Cyber-Physical Systems}, url = {https://m2.mtmt.hu/api/publication/33103738}, author = {Kombarov, Volodymyr and Sorokin, Volodymyr and Tsegelnyk, Yevgen and Plankovskyy, Sergiy and Aksonov, Yevhen and Fojtů, Olena}, booktitle = {International Conference on Reliable Systems Engineering (ICoRSE) - 2021}, doi = {10.1007/978-3-030-83368-8_6}, unique-id = {33103738}, year = {2022}, pages = {54-68}, orcid-numbers = {Kombarov, Volodymyr/0000-0002-6158-0374; Sorokin, Volodymyr/0000-0003-4494-9907; Tsegelnyk, Yevgen/0000-0003-1261-9890; Plankovskyy, Sergiy/0000-0003-2908-903X; Aksonov, Yevhen/0000-0002-2615-0598; Fojtů, Olena/0000-0003-4317-9111} } @inproceedings{MTMT:33603656, title = {Mathematical Model of the Stress State of the Antenna Radome Joint with the Load-Bearing Edging of the Skin Cutout}, url = {https://m2.mtmt.hu/api/publication/33603656}, author = {Kurennov, Sergei and Smetankina, Natalia and Pavlikov, Vladimir and Dvoretskaya, Darya and Radchenko, Vladyslava}, booktitle = {International Conference on Reliable Systems Engineering (ICoRSE) - 2021}, doi = {10.1007/978-3-030-83368-8_28}, unique-id = {33603656}, year = {2022}, pages = {287-295}, orcid-numbers = {Smetankina, Natalia/0000-0001-9528-3741; Pavlikov, Vladimir/0000-0002-6370-1758; Dvoretskaya, Darya/0000-0002-9428-5021; Radchenko, Vladyslava/0000-0003-4749-3853} } @article{MTMT:33290816, title = {Technology for programming contour milling on a CNC machine}, url = {https://m2.mtmt.hu/api/publication/33290816}, author = {Petrakov, Yuriy and Korenkov, Volodymyr and Myhovych, Artur}, doi = {10.15587/1729-4061.2022.255389}, journal-iso = {VOSTOCHNO-EVROPEISKII ZHURNAL PEREDOVYKH TEKHNOLOGII / EAST-EUR J ENTERPRISE TECH}, journal = {VOSTOCHNO-EVROPEISKII ZHURNAL PEREDOVYKH TEKHNOLOGII / EASTERN- EUROPEAN JOURNAL OF ENTERPRISE TECHNOLOGIES}, volume = {2}, unique-id = {33290816}, issn = {1729-3774}, abstract = {This paper reports a new technology for designing control programs for contour milling on CNC machines. The technology enables stabilization of the cutting process along the entire contour at the optimal level by controlling the feed, which ensures an increase in productivity when meeting the requirements for restrictions. Moreover, the effectiveness of using the technology improves with an increase in the complexity of the contour by changing the curvature of the surface. A mathematical model has been built for the interaction between the cutter and workpiece in the cutting zone when machining contours with variable curvature, which makes it possible to determine the main characteristic of the cutting process – the rate of cutting the allowance. The technology involves the use of a control program in G codes designed in any CAM system. At the first stage, a shape-formation trajectory in the form of a two-dimensional digital array is derived from the program. At the second stage, the cutter workpiece engagement in the cutting area is modeled simulated while determining the main characteristic of the cutting process – an analog of the material removal rate. And at the final stage, the simulation results are used to design a new control program, also in G-codes, with a new recorded law to control the feed, which enables the stabilization of the cutting process along the entire milling path. The software for the new technology has been developed, which automatically converts the preset control program in G-codes into a two-dimensional digital array, simulates the milling process, and designs a new control program in G-codes based on its results.

The main aim of the paper is to develop a novel algorithm that is suitable for measuring the planar burr length of such contours that cannot be scanned below. The proposed method uses a digital microscope attached to a machine tool and using existing image processing algorithms in combination with novel approaches. The advantage of the current method is that, it allows collecting the height of burr along the workpiece automatically since it is able to handle and avoid interruptions, branches and provide uniform thickness for the determined contour. Another advantage is the extended measurement ability for workpieces which contains inner contours and cannot be illuminated from below. The method was tested with sample images and also with face milling experiments, and the results were validated with the data originating from a coordinate measurement machine. The result shows a good agreement at the validation. The available accuracy mainly depends on the applied measuring equipment (resolution and magnification of camera) and set up.

This is underpinned by the fact that uniform load has a positive effect on both tool life and machining time. Unfortunately, conventional contour-parallel tool paths are unable to guarantee uniform tool loads. However, nowadays there are some advanced path generation methods which can offer a constant tool load by controlling the cutter engagement angle. Yet, the spread of these non-equidistant offsetting methods is hindered by their dependence on complex calculations. As a solution to this problem, the Fast Constant Engagement Offsetting Method (FACEOM), developed in the scope of our previous study, is seen to be taking a step towards reducing computational needs. In this paper, suggestions for further improvements of FACEOM are presented. Decreasing the number of path points to be calculated is made possible by implementing adaptive step size and spline interpolation. Through simulation tests, it was also analysed which of the numerical methods utilized for solving boundary value problems can be applied to obtain the shortest calculation time during tool path generation. The practical applicability of the algorithm has been proved by cutting experiments. With respect to research results, this paper also describes how a tool path created by the algorithm can be adapted to controllers of CNC machine tools.
