Investigations of the magneto-abrasive machining (MAM) process of ferromagnetic flat surfaces by three types of end heads were carried out. The nature of the change in the magnitude of the magnetic induction in the working zones was determined. The influence of technological parameters of the machining process was investigated, such as the feed rate of the working heads, the frequency of their rotation about their axis, the size of the working gaps on the change in the parameters of the microroughness of the machined surfaces - Sa, Sp, Sv, the frequency distribution of heights microroughness and size of the supporting surface of the profile. It was shown that the level of roughness achieved after MAM is practically the same and does not exceed, under rational conditions of the MAM process, the values Sa = 0.05-0.07 μm, Sp = 0.2 μm and Sv = 0.39 μm with the only difference that the MAM process by the heads of the "brush-half of torus" type are being realized with increased productivity, especially in terms of reducing waviness and individual elements of the heredity of machining, determined by such factors as depth and feed rate during milling. The kinetics of the formation of a microprofile of surfaces is shown under various technological conditions of the MAM process.

Abstract On the basis of recent work by Hildebrand, formulas are established for the effects of axisymmetrical edge moments and edge shears on short shells of variable wall thickness and variable meridional curvature. While the formulas are inferior in accuracy to those developed for bolted flange assemblies by Waters, Rossheim, Wesstrom, and Williams, in simplicity of use and speed of calculations, they are on a par with the well-known Geckeler formulas, without being subject to many of the limitations of the latter. The formulas are particularly suited for the analysis of the tapered hub portion of a flanged shell. Other uses are also obvious. Particular applications to redundant shell (torus-type) problems will be given in a separate paper.
