In order to better control the chips,a cutting simulation model of trapezoidal chip breaker is established by ABAQUS,and the effects of the minimum chip spacing at the tip of the trapezoidal chip breaker,the counter chip face angle and the chip breaker slope angle on the chip flow direction are studied,and the quadratic polynomial response model of the chip flow direction and these three influencing factors are analyzed and fitted by the response surface method.The results show that the smaller the spacing between chip breaker slots is,the greater the influence of counter chip face angle and chip breaker slope angle on chip flow direction is,and the greatest influence of chip breaker slope angle on chip flow direction is,followed by counter chip face angle.The quadratic polynomial mathematical model established by the response surface method can describe the influence of the minimum groove spacing at the tool tip,the counter chip surface angle and the chip breaker slope angle on the chip flow direction,and can be predicted in a certain range.
