Yucesan and Altıntaş [ 18] proposed a ball-end mill forces model based on a mechanistic relationship between cutting forces and chip load. This model discretizes the ball-end mill into a series of disks and describes in fairly rigorous detail the ball-end mill geometry and chip thickness calculation.
