An ball end mill cutter with diameter 4 mm was used for these three milling processes. All the machined blade surfaces were measured by using coordinate measuring machine (CMM) with direct method of curve surface error measuring to identify the accuracy of the machined blade surfaces. The machining and measuring results show that all these three processes can obtain good machining accuracy. And the maximum dimensional errors of the three processes were within 0.03 mm. The five-axis side milling process appears larger dimensional error on the larger distorted of the blade surface than another two processes.
