“…Therefore, it is not an easy thing to plan the processing speed well. In order to prove the effectiveness of the corrective MAF method, theoretical analysis and experimental verification are carried out, and it was proved that the surface range can be reduced from 14.317 µm to 2.18 µm by the experiments [19]. However, only a single trajectory was carried out in the previous study, and further discussion and research are still needed if this finishing is to be extended to the larger plane range.…”

“…In order to make the magnetic field of finishing tools more uniform, a lot of research was carried out to change the shape of the magnetic pole, such as adding grooves, improving finishing tracks, and so on. Since the magnetic abrasive finishing process is a machining process using a magnetic brush with flexible machining behavior, the process can be used for finishing free-form surfaces and improving surface accuracy without destroying the profile of the workpiece [17][18][19]. However, because the magnetic brush is not a uniform finishing tool, further research is still needed to maintain the geometric accuracy of the workpiece or correct the geometry, which is also the research content of this subject.…”

In order to improve the plane quality of the workpiece shape accuracy, a correction abrasive finishing method is proposed. This method is used to achieve the effect of correcting the workpiece surface by changing the finishing conditions of different areas according to the profile of the initial surface, such as feed speed. In previous research, the feasibility and effectiveness of this method were proven. In this research, a theoretical analysis of this method was carried out and the extension of this method to the processing of larger planes was studied. Through a series of experiments on an aluminum plate (A5052), it was proven that the shape accuracy of the workpiece surface can be effectively corrected by accurately controlling the feed speed. The experimental results showed that the extreme difference of the workpiece can be reduced from 4.81 μm to 2.65 μm within the processed area of 30 mm by 10 mm.

“…Earlier it was shown that the shaping of these miniature surfaces by the methods usual for larger-sized products is practically impossible due to the low rigidity of the workpiece being processed [7,8]. However, in [9,10], a special strategy was proposed for processing cycloidal helical surfaces with different types of cross-section, which allows ensuring the required shape accuracy for given cross-section diameters ( Fig. 3).…”

The working bodies of screw volumetric machines are complex-profile cycloidal screw surfaces. This article deals with the problem of technological preparation for the production of such surfaces, associated with the uncertainty of the technological capabilities of a special processing strategy. To solve this problem, an analytical expression of the criterion was proposed, which makes it possible to assess the applicability of the processing strategy for the given geometric parameters. The adequacy of the proposed criterion is confirmed by machine and natural experiments.

“…The geometry of working part of the taps, particularly their cutting edges, has a complex space shape. The modes and conditions of MAM of the taps will be significantly different from the machining modes of other cutting tools (Baron, 2008;Denkena et al, 2014;Karpuschewski et al, 2009;Keksin, 2013;Maiboroda et al, 2012Maiboroda et al, , 2017Maksarov and Keksin, 2018). A great influence on the quality indexes of the tools have features of location of the taps in the working zone of the machine, rotation speed, value of magnetic induction, type and fraction of the magneto-abrasive powder.…”

The features of magneto-abrasive machining of taps for metric thread cutting were investigated. The calculation method of integral intensity of the magneto-abrasive machining of the working surfaces of the taps by the quantitative values of normal and tangential components of moving speed of the quasi-stable volumes of the magneto-abrasive tool was developed. Based on the results of calculations, it was possible to predict the probable influence of the taps’ location in the working zone on the quality and efficiency of machining their working surfaces. The calculation method is relevant for taps of all diameters with a profile angle of 60°. The working surfaces of the tool would not be effectively machined if the location angle of taps to the plane of the working zone of the machine equals 20–60°. Depending on the expected major polishing or strengthening effect of magneto-abrasive machining, the taps are required to be located at an angle of 60–90° to the plane of the working zone of the machine.
