• ### Determination of Force Parameters for Milling Simulations

Milling is a machining process in which material removal occurs due to the rotary motion of a cutting tool relative to a typically stationary workpiece. In modern machining centers up to and exceeding six degrees of freedom for motion relative to the tool and workpiece are possible which results in a very complex chip and force formation.
