摘　　要：为研究轴向车铣加工等距型面的切削过程,针对其运动过程复杂的特点,以矢量为研究对象,通过矢量分析建立描述其运动过程的数学模型,并给出基本矢量方程。通过数学模型对加工的运动轨迹进行仿真,分析主要切削参数对运动轨迹的影响。为验证运动矢量模型的正确性,进行等距型面的轴向车铣加工试验,得到包含内外轮廓等距型面的加工样件。结果表明,采用轴向车铣完全可以实现等距型面的内外轮廓加工,理论上只要增大铣刀与工件的转速比就可以得到足够小的工件表面粗糙度,且选用逆铣的切削方式更容易得到光滑的加工表面。For researching the cutting process of axial turn-milling of equidistant profile, in view of the complexity of its motion process, and with vector as the research object, a mathematical model describing its movement process is founded through vector analysis, and the basic vector equation is given. The movement track of machining is simulated through the mathematical model. The influence of main cutting parameters on the movement track is analyzed. For verifying the correctness of the movement vector model the experiment of axial turn-milling of equidistant profile is carried out, and the machining sample of equidistant profile containing inner and outer contours is obtained. The result shows that machining inner and outer contours of equidistant profile can be realized completely by adopting the axial turn-milling. Theoretically, provided that the rotating speed ratio between milling cutter and work piece is augmented, adequately small surface roughness of work piece can be obtained, and smooth machined surface can be obtained more easily by using up-milling.
