This study describes a new method to achieve the high precision end-milling on a 5-axis controlled machining center. We attracted attention to multi-blade end-mill tools with high helix angle in order to keep a constant cutting force in side milling. It is well known that the convex and concave error on the machined sidewall surface is generated due to the variation of cutting force in end-milling using the multi-blade end-mill tools. On the other hand, the constant cutting force is obtained in end-milling adequate thickness workpiece using the multi-blade end-mill tools with high helix angle. The constant cutting force makes it possible to decrease the machined surface error due to the variation of cutting force. Therefore, we propose a method of tilting the workpiece by controlling A or B axis in order to obtain a proper cutting thickness of sidewall.
