摘　　要：现有的几种微细金属切削加工精度提升方法没有准确计算切削区域的梯度位移,导致精度提升效果不理想,设计一个新的微细金属切削加工精度的有效提升方法。建立微细金属切削加工错位本构关系,计算错位本构关系中密度函数,计算切削区域应变梯度位移,获得切削加工的位移变化量,建立微细金属切削加工精度优化模型。The existing methods for improving the machining accuracy of micro metal cutting do not accurately calculate the gradient displacement of the cutting area,which leads to the unsatisfactory effect of accuracy improvement.A new effective method for improving the machining accuracy of micro metal cutting is designed.The dislocation constitutive relation of micro metal cutting is established,the density function of dislocation constitutive relation is calculated,the strain gradient displacement of cutting area is calculated,the displacement variation of cutting is obtained,and the precision optimization model of micro metal cutting is established.
