建议在刀具前刀面上沿着切屑流动形成各种深度为 7-149 μm、深宽比为 0.14-0.50 的无涂层微槽。目的是了解微槽形状和尺寸如何影响钛合金干车削中的切削温度和切削力。首先，采用金刚石砂轮V型刀尖进行微磨削，加工出精确、光滑的微槽；然后进行材料去除率的干车削实验；最后，研究了切削温度、切削力和刀具磨损。结果表明，刀具前刀面上的这些微槽有助于减少切屑摩擦并排除切削热。与传统平面刀具相比，微槽刀具可将切削温度降低 103 °C 甚至更多。对于传统平面刀具，预测的切削尖端温度可达约 1322 °C，但对于微槽刀具，其切削尖端温度仅为约 500 °C。此外，除了微槽深度为 7 μm 的情况外，随着微槽深度的减小，切削温度降低，剪切角增大。 25μm深微槽刀具在较大材料去除率车削中更大程度地降低切削温度和切削力。在使用微槽刀具进行干车削时，要求微槽宽度小于切屑宽度，并且其深宽比足够大，以保持切屑背面和刀具前刀面之间的空气间隙。
Various non-coated micro-grooves with 7–149 μm in depth and 0.14–0.50 in aspect ratio are proposed on tool rake surfaces along cutting chip flowing. The objective is to understand how the micro-groove shape and size influence cutting temperature and cutting force in dry turning of titanium alloy. First, the micro-grinding with a diamond wheel V-tip was employed to fabricate accurate and smooth micro-grooves; then dry turning experiments were performed with regard to material removal rate; finally, cutting temperature, cutting force and tool wear were investigated. It is shown that these micro-grooves patterned on tool rake surface contribute to decreasing cutting chip frictions and excluding cutting heat. The micro-grooved tool decreases cutting temperature by 103 °C and more against traditional plane tool. The predicted cutting tip temperature reaches about 1322 °C for traditional plane tool, but it does only about 500 °C for micro-grooved tool. Moreover, the cutting temperature decreases and the shear angle increases with decreasing micro-groove depth except for the case of 7 μm in micro-groove depth. The 25-μm-depth micro-grooved tool decreases cutting temperature and cutting force more greatly in larger material removal rate turning. In the dry turning with a micro-grooved tool, it is required that the micro-groove width is less than cutting chip width and its aspect ratio is enough large to maintain the air spaces between chip back surface and tool rake surface.
