Abstract
Vibration-assisted cutting (VAC) with polycrystalline diamond (PCD) tool refers to the cutting with certain amplitude and high frequency tool vibration, which can definitely reduce the cutting force and tool wear compared with conventional cutting (CC). In this paper, a plane strain orthogonal model for PCD tool cutting steel AISI 1045 is established by using the finite element software ABAQUS/explicit. Then the cutting force of VAC compared with CC is explained. The value and distribution of cutting force at different depths of cutting is analyzed. It is also studied the effects of vibration frequency and amplitude on cutting force and thrust force during the ultra-precision cutting process. Afterwards, optimum selection of process parameters is presented for VAC processing of steel AISI 1045.
