This study deals with geometric analysis of workpiece removal in multi axis control machining with ball end mill. In order to predict both surface roughness and accuracy of workpiece shape in finish machining process, it is required to apply a new estimation method which can cope with quite small feed rate in cutting conditions. So, in this study, we introduce the developed removal model of workpiece, which is designed to consider influences of cutting edge roundness. And, we analyze both removal depth on each cutter mark and cutting error on workpiece shape, for a case of ball end mill with a throwaway chip. From results, we can find that distribution of removal depth on cutter mark is strongly influenced by tool posture and shape error caused by tool deflection is often bigger than height of cusps.
