为了对轴向车铣加工的切屑进行仿真,通过运动的矢量方程,给出了切屑仿真的数学模型,阐述了切屑形状的计算机仿真原理,并通过仿真得到了不同工艺参数下的切屑形状.分析切屑仿真结果可知,轴向车铣切屑由相互垂直且相连的两部分组成,由于切削厚度的变化致使切屑变形不均匀,极薄的切入和切出预示着在轴向车铣过程中,铣刀刃口的圆弧半径对精加工表面有较大影响. In order to simulate the chip in the axial lathe milling process, a mathematical model of the chip simulation is given by the vector equations of motion, the computer simulation principle of the chip shape is expounded, and the chip shape under different process parameters is obtained by simulation. The results of the chip simulation show that the axial turning and milling chip consists of two parts which are perpendicular to each other and connected to each other. Due to the variation of the cutting thickness, the chip deformation is not uniform. The extremely thin cutting and cutting indicates that in the process of axial turning and milling, Edge radius of the arc on the finishing surface has a greater impact.
