Abstract. This paper deals with the analysis of the surface generating mechanism of a ball end mill based on deflection. The FEM model of a ball end mill is made out and the cutter deflection due to cutting force is calculated using the model and the cutting edge position is predicted using the behavior of cutting force obtained by the cutting tests and cutting area calculated by 3D-CAD.

This paper deals with an analysis of the chip area by ball end milling of an inclined surface using a contour path method. At first, the modeling of a cutter, an edge, a rake surface and a workpiece with an inclined surface are carried out using 3D-CAD. Secondly, the chip area is calculated by the interference of the rake surface and the chip ...

In this paper, cutting mechanism and cutting performance of ball end mill for spherical surface with contour path method is investigated. Ball end mills are used to produce molds, dies and so on. However, the edge shape is complex, so cutting process is not clear. Then, it is not clear effectively using method of the tool based on good cutting performance.

For the ball-end milling, the machining process consists of successive parallel cutting paths separated by an offset distance (the offset between the successive paths is called the pick in this paper). As shown in Fig. 2 (a), due to the spherical geometry, a path-interval scallop can be observed between successive paths.
