Abstract: 
An instantaneous rigid force model for prediction of cutting forces in ball-end milling ‎of sculptured surfaces is presented in this paper. A commercially available geometric ‎engine is used to represent the cutting edge, cutter and updated part geometries. The ‎cutter used in this work an insert type ball-end mill. Intersecting an inclined plane ‎with the cutter ball nose generates the cutting edge. Immersion geometry along the ‎tool path is computed using the contact face between the ball-end mill and the solid ‎model of the updated part. The engaged portion of the cutting edge is divided into ‎small differential oblique cutting edge segments. Friction, shear angles and shear ‎stresses are obtained from orthogonal cutting data available in the open literature. For ‎each tool rotational position, the cutting force components are calculated by ‎summation of the differential cutting forces. The developed model has been verified ‎through experiments performed on several work pieces with different front and side ‎angles. The predicted cutting forces have shown good agreement with experimental ‎results. The developed model can be used as an efficient tool for predicting cutting ‎performance in ball-end milling of sculptured surfaces of dies and moulds‏.‏
