The influence of parameters of linear flat bottom chip breaker on chip flow

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