Article Preview

High-speed machining aluminum alloy blades, often can generate chatter. The static modal experiment and dynamic cutting test method was used to get the influence factors. It studied the change of blade modal during the material removal process according the experiments since the thin blade and large influence to its stability of the removal of blank. Through the study it was found that there are two modes of blades within the scope of sensor’s detecting. Blade modal frequency appears to first increase then decrease during the material removal process with little vibration. The dynamic experiment analysis the factor of cutting force in five-axis milling process and messures five-axis machining cutting force in various parameters. It was observe that distribution of 3-dimension cutting forces in cutting path. It was found that the distribution rule of cutting force. Resultant cutting force was increased with cutting speed increased.
