Ball end mills are widely used in machining of parts with sculptured surfaces. The properties required for ball end milling are high productivity, high machining accuracy and integrity of machined surface. In this study the machining error theory is applied to the analysis of spherical surfaces. The workpiece material used is plain carbon steel. Cutting tool is a cobalt enriched highspeed steel (Co-HSS) ball end mill. The machining errors are examined for various cutting conditions and cutting modes. The machining error in up cross-feed is lager than that in down crossfeed. Furthermore, it is seen that the influence of cross-feed on machining error is largest in the cutting mode of down cross-feed and down cut.
