Abstract
The simulation model of cutting TC4 titanium alloy with a YG8 cemented carbide tool is established through ABAQUS. The minimum width of the chip breaker, anti-chip surface angle, bevel angle of chip breaker, and the change of chip breaker front angle at the tooltip are changed by controlling other chip breaker parameters unchanged. Orthogonal tests are established under different edge angles to analyze the influence of the relevant parameters of the chip breaker on the chip angle and the influence of the change of the chip breaker parameters on the chip angle under different inclination angles. The results show that the chip breaker parameters affect the chip flow direction. The larger the groove spacing is, the smaller the chip flow angle first decreases and then becomes stable. The chip flow angle increases with the increase of the anti-chip surface angle, bevel angle of the chip breaker, and chip breaker front angle. The larger the inclination angle is, the more obvious the influence of chip breaker parameters is.
