Abstract The article discusses the issues of assessing the effectiveness of the use of new diffusion-alloyed ferromagnetic abrasive materials in the technology of magnetic abrasive finishing. The productivity of processing and the roughness of the processed surface were evaluated as they are considered to be the main performance criteria of ferric-abrasive powders (FAP). There were researched three types of powders: common Fe-TiC powder, obtained by the sintering (as a reference), and two new diffusion alloyed (borated and nitrocarburized) FAP, made of low-carbon finely dispersed ferrum-based wastes. Both new proposed diffusion-alloyed powders have better cutting characteristics then reference powder, explained by the structure features and their properties. Evaluation of productivity and roughness of surface shows, that there is their direct dependence of morphology, hardness and fragility of powder particles. The best cutting characteristics has borated powders, as they have microhardness 18,000-20,000 MPa and the tendency to brittle fracture, that leads to the new less-sized particles with sharp cutting edges creation.

In this paper the Magnetic Abrasive Finishing (MAF) was utilized after Single Point Incremental Forming (SPIF) process as a combined finishing process. Firstly, the Single Point Incremental forming was form the truncated cone made from low carbon steel (1008-AISI) based on Z-level tool path then the magnetic abrasive finishing process was applied on the surface of the formed product. Box-Behnken design of experiment in Minitab 17 software was used in this study. The influences of different parameters (feed rate, machining step size, coil current and spindle speed) on change in Micro-Vickers hardness were studied. The maximum and minimum change in Micro-Vickers hardness that achieved from all the experiments were (40.4 and 1.1) respectively. The contribution percent of (feed rate, machining step size, coil current and spindle speed) were (7.1, 18.068, 17.376 and 37.894) % respectively. After MAF process all the micro surface cracks that generated on the workpiece surface was completely removed from the surface.

High quality, highly efficient finishing processes are required for finishing difficult-to-machine materials. Magnetic abrasive finishing (MAF) process is a finishing method that can obtain a high accuracy surface using fine magnetic particles and abrasive particles, but has poor finishing efficiency. On the contrary, fixed abrasive polishing (FAP) is a polishing process can obtain high material removal efficiency but often cannot provide a high-quality surface at the nano-scale. Therefore, this work proposes a new finishing process, which combines the magnetic abrasive finishing process and the fixed abrasive polishing process (MAF-FAP). To verify the proposed methodology, a finishing device was developed and finishing experiments on alumina ceramic plates were performed. Furthermore, the mechanism of the MAF-FAP process was investigated. In addition, the influence of process parameters on finishing characteristics is discussed. According to the experimental results, this process can achieve high-efficiency finishing of brittle hard materials (alumina ceramics) and can obtain nano-scale surfaces. The surface roughness of the alumina ceramic plate is improved from 202.11 nm Ra to 3.67 nm Ra within 30 min.

Blanks made from sheet steel or other materials have burrs on their edges. The burrs are formed on the blanks at cutting down or processing of them by cutting tools. Removing of the burrs requires a lot of manual work. Frequently the blanks have small rigidity, and it especially complicates removal of the burrs. This article describes intensification of the magnetic abrasive finishing method (MAF) with a goal to eliminate the manual deburring and to raise productivity of deburring on the flexible blanks. The study goal was achieved by optimization of MAF conditions and a of the work area geometrical form.
