Abstract

In the present study, a novel body-armor-like abrasive tool (BAAT) was designed with the “particle cluster” effect to realize a high-shear and low-pressure grinding. The finite element method (FEM) was utilized to analyze the interplay of the abrasive layer and the micro convex peak (MCP) of the workpiece during the grinding process with the BAAT. An experimental platform was established to explore the high-shear and low-pressure grinding phenomenon and verify the simulation results. The simulation results showed that the BAAT formed a “particle cluster” effect when contacting MCP. The ratio of the tangential force and the normal force was greater than 0.33, which was identical to the experimental results. The BAAT demonstrated the strongest hindrance to the MCP. In the absence of Kevlar, the degree of energy dissipation was lower compared to the BAAT. The kinetic energy dissipation of the MCP was the smallest without abrasive particles. The maximum displacement of the Kevlar in the case of Kevlar was only 4.85 mm. The displacement of Kevlar in the BAAT was 1.81 mm. The degree of decline had been reduced by 62.6%. Comparing the speed of the MCP, the speed least dropped when only Kevlar existed. The trend of speed variation coincided well with that of kinetic energy.
