摘　　要：微小型正交车铣切屑变形单因素试验结果证实切削速度是影响切屑形态的重要参数.为了分析切削速度与切屑变形的关系,在介绍车铣切削过程及切屑形成机理的基础上,利用能量平衡原理导出的任意切削速度下的剪切角关系式,从理论角度合理解释了切削速度对切屑变形的影响以及随着切削速度提高使切屑形态逐渐变直的现象.The results of chip-deformation single factor test of the micro orthogonal turn-milling showed that the cutting speed is the important parameter of effect the chip shape. In order to analyze the relationship between the cutting speed and the chip-deformation, using shear angle expressions under the any cutting speed based on the energy balance principle, to explain reasonably that the influence of cutting speed on chip-deformation, as well as the phenomenon of the chip shape becoming straight gradually along with the cutting speed improving from the theory perspective, after introducing the turn-milling cutting process and the chip-formed mechanism.
