Technological assurance of the quality of processing of products from aluminum alloys with a complex geometric shape using magnetic abrasive processing

Abstract

In the presented article, the issue of the implementation of magnetic abrasive processing is considered in order to ensure the quality of surfaces of complex shapes of parts made of corrosion-resistant aluminum alloys. The implementation was carried out through theoretical and experimental research. In a theoretical study, the features of processing corrosion-resistant aluminum alloys, existing and possible schemes for magnetic-abrasive processing of surfaces of complex geometric shapes, including a combination of various working movements of the workpiece and pole pieces, are considered. In an experimental study, the dependence of the quality of the processed surface (roughness) on the size of the working gap between the workpiece and the working pole was determined. The result of the research is the determination of the optimal treatment schemes for surfaces with a complex geometric shape, as well as the derived exponential dependence of the change in surface roughness on the size of the working gap.

Influence of process parameters on magnetic abrasive machining efficiency

“…where Q is the mass of the material to be removed, determined by the difference in masses to 𝑄 before and after 𝑄 after MAM; S is the surface area to be treated, cm 2 . Based on a literature review [1,4,6] and the capabilities of a dedicated magnetic blasting facility, two varying parameters were selected that have the greatest influence on the material removal process from the workpiece surface. These parameters include machining time and electromagnetic induction value (Table 1).…”

“…This is a state-of-the-art machining approach that allows a high-quality machined product to be produced with minimal surface thermal defects. This method is widely used in the machining of linear and cylindrical parts made of aluminium, brass, steel and other materials [5,7,8].…”

Features of mechanical processing of aluminum alloys

“…In addition, they are relatively easy to shape, especially with the help of mechanical cutting [2]. In fact, aluminum and its alloys are considered to be easily workable materials compared to other light materials, such as titanium and magnesium alloys [3,4].…”
