### 3D Ball-End Milling Force Model Using Instantaneous

Application of a ball-end milling process model to a CAD/CAM or CAPP system requires a generalized methodology to determine the cutting force coefficients for different cutting conditions. In this paper we propose a mechanistic cutting force model for 3D ball-end milling using instantaneous cutting force coefficients that are independent of
