The main purpose of this paper is to study the change law of the contact condition between the fine drilling tool and the workpiece surface during cutting. Firstly, the structure of the drill tip of the fine drilling tool is analyzed, and the contact force of the drill tip is effectively decomposed. Then, on the basis of considering the cutting edge radius, the cutting mechanics model of each part of the drill tip was established according to the theory of slip line field. Finally, drilling experiments under different cutting conditions were carried out to solve the contact coefficient between the tool and the workpiece surface. The research shows that the high feed leads to greater ploughing effect in cutting, resulting in sharp change of contact force, which provides a research direction for tool tip design.
