Abstract: In the past, researches mainly focused on the feasibility of the vibration assisted grinding in machining some brittle materials and the mechanism study is still absent. In this paper, an analytical model is presented to interpret the material removal mechanism of vibration assisted grinding brittle material. The model investigates the cutting kinematics of single grinding grain and the stress condition alone the equivalent shear plane within the chip formation zone. The theoretical analysis combined with the experimental result show that the proposed analytical model can be used to explain the material removal mechanism of vibration assistance grinding of brittle material.

Keywords: Elliptic vibration-assisted grinding, Material removal mechanism, Equivalent shear plane, Brittle material, Stress condition.
