This study makes an effort to develop a theoretical model by which the machining error for arbitrary cutting direction in ball end milling of cylindrical surface can be predicted. At first, instantaneous cutting force is calculated following the analysis of undeformed chip thickness. Secondly, tool deflection is estimated by the calculated instantaneous cutting force. At last, machining error is evaluated with tool deflection. To verify this theoretical model, the experiments are carried out, and the theoretical machining error is compared with the measured machining error. The influences of cutting direction in different cutting conditions are clarified with predicted and measured machining errors. Furthermore, the appropriate cutting conditions for different cutting modes are discussed.
