摘要：

In this paper, in order to obtain the best tool path in NC machining, the influence of workpiece curvature on the change of cutting force in NC machining is analyzed. Based on differential geometry, the normal curvature mathematic model of every point on ellipsoid along with the cutting direction is built. Using the MATLAB software, the relationship between the normal curvature of freeform surface and cutting force is established. The cutting force decreases while the normal curvature increases. To verify the relationship, the experiment is performed and the experimental result accords with the theoretic prediction. The establishment of this theory provides the theoretic base for optimizing tool path in NC machining.
