| Abstract: | The authors proposed using Pythagorean hodograph spirals in approaching and corner turning for high speed milling to reduce jerks in motion and so that the tool life is lengthened, and the effective machining speed and machining accuracy are improved. Formulas of the PH transition curves were given and simu lations were conducted to demonstrate and verify the significance of the proposed method. |
