The shaping process of surface texture is complicated and depends on many factors and phenomena accompanying them. This article presents the author's test stand for the measurement of relative displacements in a tool-workpiece system during longitudinal turning. The aim of this study was to determine the influence of edge radius on the relative displacement between the tool and workpiece. The cutting process was carried out with inserts with different edge radii for X37CrMoV5-1 steel. As a result of the research, vibration charts of the tool-workpiece system were obtained. In the range of feed 0.03-0.18 mm/rev, the values of the standard deviation of relative displacements in the -axis were obtained in the range of 0.36-0.78 μm for the insert with an edge radius of = 48.8 μm. As a result of the work, it was determined that for the feed value of 0.12 mm/rev for all inserts, the relative displacements are the smallest. As the final effect, the formula for forecasting the Ra roughness parameter was presented.
表面纹理的形成过程很复杂，取决于许多因素以及伴随它们的各种现象。本文介绍了作者用于测量纵向车削时刀具 - 工件系统中相对位移的试验台。本研究的目的是确定刃口半径对刀具与工件之间相对位移的影响。采用不同刃口半径的刀片对X37CrMoV5 - 1钢进行切削加工。研究结果得到了刀具 - 工件系统的振动图表。在进给量为0.03 - 0.18 mm/rev的范围内，刃口半径为 = 48.8 μm的刀片在 - 轴上相对位移的标准偏差值在0.36 - 0.78 μm范围内。研究结果表明，对于所有刀片，进给量为0.12 mm/rev时，相对位移最小。作为最终成果，给出了预测Ra粗糙度参数的公式。
