Numerical and experimental investigation of contact length during orthogonal cutting

Abstract In this paper, the influence of the chip thicknesses on the contact length between the rake face of the tool and the chip is investigated during orthogonal cutting. This is an important parameter in metal cutting, since it determines the cutting force over the rake face and the heat transfer between the tool and the workpiece. Therefore, it plays significant role in the theoretical cutting force models and in the dynamics of cutting processes. This paper is dedicated to determine the contact length based on experimental methods and finite element analysis (FEA) using the so-called Coupled Eulerian-Lagrangian (CEL) formulation.
