Moulds and dies with sculptured surfaces are usually finished using a three-axis computer numerically controlled milling machine with a ball-end mill. In this paper, the surface shapes are defined by a rectangular grid of surface points and the inverse offset method (IOM) is used to generate the cutter paths.

Aiming at the machining process of the ball-end milling cutter in the mold splicing area, the impact at the moment of contact between the cutter and the workpiece is analyzed. The instantaneous chip thickness model that considers impact factors and the state model that calibrates the cutting state by coefficients is established.

End milling is a machining process used to cut or shape materials using a rotating milling cutter called an end mill. It's employed in most manufacturing sectors for profile cutting, slot drilling, and contouring. The end mill's cylindrical milling cutter has cutting edges on both the bottom and the side to remove material from a workpiece.
