| Abstract: | Cutting force model was developed. The chip thickness relationship among cutter deflection, cutter feed and so on was established based on cutter spring deflection model and cutter run out. Then ,an embed convergence algorithm of milling force was proposed. At last ,the cutting force model is validated through cutting tests. |

| Keywords: | ball end mill cutting force model spring deflection instantaneous cutting thickness model |
