Accuracy of machined components is one of the most critical considerations for any manufacturer. However, when milling the radial force deflects the cutting tool and workpiece. It affects the precision and quality of machined surfaces. The extent of the deviations can be predicted in various mathematical models. Thus, the errors can be compensated in NC programme effectively. So it is possible to machine with high cutting conditions, and also a high quality of machined surface can be achieved. In this paper are predicted deflection of milling tools and thin-walled workpiece. The experimental results show that the overall error in the flexible milling can be captured and predicted with very high accuracy.
