本文从刀具几何参数和加工条件两个方面,对斜角切削的流屑方向进行了分析,提出了流屑角的数学模型。介绍了用工具显微镜测量流屑角的方法。实验表明:流屑角的计算值与实测值基本一致。文中还提出,随着法向前角增大,流屑方向将愈接近前刀面最大倾斜方向。 In this paper, the direction of chip flow in bevel cutting is analyzed from two aspects of tool geometry parameters and processing conditions. The mathematical model of chip flow angle is proposed. The method of measuring the shedding angle with a tool microscope is introduced. Experiments show that: the calculated value of the chip angle is basically consistent with the measured value. It is also suggested in the paper that as the normal rake angle increases, the direction of the flow debris will be closer to the maximum inclination of the rake face.
