This paper deals with analysis of the cutting mechanism of ball end mill for milling of inclined surface. At first, modeling method for a tool and a workipece by 3D-CAD and calculating method of cutting area are shown. Secondly, cutting areas are calculated by the 3D-CAD models and cutting force are obtained by cutting tests. And also, the relationship between cutting torques and estimated values as cutting performance and inclined angles of the workpiece are discussed by the results.
