Abstract
The Ti-6Al-4V with significant anisotropy was taken as the research object to analyze the influence of sampling direction and cutting speed on the chip morphology. Based on the fracture damage model of Ti-6Al-4V which was constructed in the previous stage, high-speed orthogonal cutting simulation was carried out in finite element software. The accuracy of the model was verified by cutting experiments. The chip morphology was quantitatively characterized by the chip segmentation degree and chip segmentation frequency. The results showed that the accuracy of the model was high, and it could accurately reproduce the chip formation process of the material in the high-speed cutting process. It was found that material direction and cutting speed had significant effects on chip morphology. When the cutting speed was constant, the chip morphology under different directions was different. The critical cutting speed of chip changing from serrated chips to fragmented chips was different when the direction ranged from 0° to 90°.
