The article presents a mathematical model for determining mounting dimensions and bearing surface parameters of die heads equipped with circular radial chasers, with due regard for the specifics of cutting kinematics and position of surface-shaping points on the cutting edge of the tool. The study analytically establishes the connection between structural and geometric parameters of the threaded coupling between the chaser and the workpiece, which means that the cutting edge design and geometry can be analysed further in terms of ensuring that the chaser parts performing cutting and calibrating function properly. The article supplies results of calculations demonstrating the effect of die head mounting dimensions on clearance angle values of elementary cutting profiles and area increment history of chaser bearing surfaces.
