This paper deals with the theoretical and experimental analysis on the machining accuracy of the corner cutting and the slotting in end mill operations. The machining accuracy of a side surface is calculated by the instantaneous cutting force and the static compliances of an end mill, the tool and the workpiece holding systems in the direction normal to the machining surface. The accuracy of a bottom surface is calculated by adding the over-cutting error due to the bending deflection of the end mill to the displacements of the two holding systems in the direction of the end mill axis. The results obtained are as follows : (1) The accuracy of the machined surface can be predicted if not only the compliance of the end mill but also those of the tool and the workpiece holders are taken into consideration. (2) Up milling is recommended from the point of view of the side surface accuracy. (3) There is no significant difference in the accuracy of the bottom surface between up milling and down milling.
