摘　　要：为更好地控制切屑,通过ABAQUS建立了梯形断屑槽的切削有限元仿真模型,研究了梯形断屑槽参数中刀尖处最小槽间距、反屑面角、断屑槽斜角对切屑流向的影响,并通过响应面法分析并拟合出切屑流向与这三个影响因子的二次多项式响应模型。结果表明:断屑槽槽间距越小,反屑面角、断屑槽斜角对切屑流向的影响越大,且断屑槽斜角对切屑流向的影响最大,反屑面角次之。通过响应面法建立的二次多项式数学模型能够描述刀尖处的最小槽间距、反屑面角、断屑槽斜角对切屑流向的影响规律,并且可以在一定范围内进行预测。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.
