“…In recent years, the STF has been applied in the novel loose abrasive machining such as shear thickening polishing 20 and magnetic shear thickening finishing. 21 Similar concept was proposed to apply in the fixed abrasive machining to achieve the high-shear and low-pressure grinding. The abrasive tool was developed with flexible composite, that is, warp-knitted spacer fabric and STF.…”

In this work, a novel grinding method using a special abrasive tool was first proposed to achieve high tangential grinding force and low normal grinding force. The abrasive tool was developed with flexible composites to remove workpiece materials under “high-shear and low-pressure” grinding mode. The concept of the high-shear and low-pressure grinding method was introduced in detail. Grinding tests were carried out on a precision grinder with the developed abrasive tool for single crystal silicon specimens. The results showed that the grinding force ratio between tangential force and normal force for the proposed grinding method was ranged between 0.9 and 1.3, which was three times larger than that of the conventional grinding method. It was verified that the developed abrasive tool possessed the grinding characteristics of high tangential grinding force and low normal grinding force. After grinding of silicon specimens for 120 min, the value of surface roughness decreased from 429.20 to 32.91 nm under the selected grinding conditions. The surface quality of the silicon specimens was greatly improved after grinding.

In this study, a CBN liquid-body-armor-like grinding wheel was developed for high-shear and low-pressure (HSLP) grinding of Inconel718 alloy. The material removal mechanism of the novel CBN liquid-body-armor-like wheel was introduced in detail. Particle clustering effect of the new wheel was studied via the finite element method. A series of grinding tests were carried out to investigate the grinding performance under the various conditions. It was shown that the surface roughness Ra of the ground workpiece decreased from initial 0.3 to 0.094 μm. Simultaneously, the specific material removal rate of 1.069 × 105 μm3/mm·s was attained. The power spectral density function (PSDF) was employed to reveal the percentage of waviness and roughness of the surface profile, which was mainly concentrated in 0–40k Hz as compared with 60–120k Hz before grinding. It indicated that particle clustering effect was generated in the grinding zone. Besides, the maximum peak amplitude of the cross-correlation function coefficient of the ground workpiece surfaces before and after grinding was less than 0.3. The original scratches were completely removed. New and smooth textures generated after grinding. The experimental results demonstrated that the newly developed CBN liquid-body-armor-like grinding wheel was effective for surface finishing of the Inconel718 workpiece.

“…In MRF, Liu et al 16 reported that the volumetric removal rate and normalized peak increased with the spindle speed and noted that the polishing spot length increased while the width decreased. Fan et al 17 used shear thickening fluid to polish Ti-6Al-4V workpiece surface and reduced surface roughness to 54 nm from 1.17 µm without any appreciable scratches on the surface. Khatri et al 18 studied the effect of current, wheel speed and working gap on finishing of diamond-turned EN 31 workpiece material and reported that surface roughness reduced with increasing wheel speed.…”

Magnetorheological fluid-based finishing is one of the recognized techniques for precisely finishing of a variety of components. Material removal depends largely on velocity and compression of the magnetorheological (MR) fluid ribbon when it interacts with the workpiece. This article studies the throwing of magnetic and abrasive particles during carrier wheel rotation. Theoretically computed centrifugal and magnetic forces are balanced against each other to determine the speed at which these particles are ejected from the MR fluid. The results of experiments at various carrier wheel speeds show the reduction of MR fluid ribbon thickness at higher wheel speed due to throwing of MR fluid. As a result of particle separation from the MR fluid at high rotational speed. As the carrier wheel speed increases, surface roughness decreases initially and then increases. There is good agreement between theoretical and actual results for the spindle speed at which magnetic particles depart the MR fluid ribbon.
