Abstract

During the cutting process of chamfered tools, The Dead Metal Zone (DMZ) forms at the front of the chamfer, interacting with the workpiece through friction and generating an additional heat source that affects the tool's cutting temperature. This paper analyzes the cutting model of chamfered tools considering the effect of DMZ and establishes the relationship between cutting force and tool geometric parameters. The cutting force is used to determine the magnitude of the heat source during the cutting. Using the semi-boundary heat transfer principles, the temperature rise of the tool's flank face is calculated. Finite element simulations of chamfered tool cutting on AISI-1045 steel are conducted, and the resulting temperature rise is compared with theoretical calculations. The temperature distribution of the chamfered tool is obtained, along with the determination of heat source distribution coefficients and heat partition fractions on the flank face.
