Finishing end mills which can reduce dimensional inaccuracy and surface profile error in the finish process of end milling are presented. Computer simulation against chip geometry and variable distance from work surface to cutter axis are performed for the design of cutter shape with high rigidity. The performance of newly developed end mills are verified through the measurement of spiral chip diameter, cutting force variation and surface profile error in the face milling. it is shown that the magnitude of surface profile error can be reduced from 60% to 70% by the newly developed end mills, compared with the standard type. While the characteristic of surface profile error remains unchanged, for the cutter geometry with standard pitch was adopted. The cutter also possess a sufficient space to extrude chips which are produced in the finish process of end milling.
