* <$<$本研究涉及具有平坦端部的V形微槽的产生。端面平坦的微槽在产生断续槽时起着重要作用。通过使用旋转V形切削工具的微槽在中途停止时具有大半径的长圆弧斜率。因此，采用非旋转的V形切削工具，然而，在微槽的端点处仍然形成斜面。在本研究中，我们设计了两种新的切割方法，以产生具有平坦端部的V形微槽。第一种方法是利用切屑的生成，在一定的切削条件下切屑的形状是直的。非旋转切削工具将垂直产生的切屑压向V形微槽，并在平面上切削切屑的多余部分。第二种是将不旋转的V形刀具垂直于工件表面，向后进给，通过反向进给去除膨胀部分。从实验结果中，它被发现，该方法能够创建平端微槽。
*** † †† The study deals with the creation of V-shaped microgrooves with flat-end. Microgrooves with flat-end play an important role in case of generating intermittent grooves. Microgrooves by use of a rotational V-shaped cutting tool have a long circular arc slope with a large radius when stopping on the way. Thus, a non-rotational V-shaped cutting tool is employed, however, a slope is still formed at the end point of the microgroove. In the study, two new cutting methods are devised so that the V-shaped microgrooves with flat-end can be created. The first method makes use of chip generation whose shape is straight under some cutting condition. The non-rotational cutting tool presses the chips generated perpendicularly against the V-shaped microgroove and cuts the excessive parts of chips over the plane. The second one is to stick the non-rotational V-shaped cutting tool perpendicular to the workpiece surface, to feed it backwards and to remove the swelled parts by feed it to the reverse direction. From experimental results, it is found that the methods enable the creation of flat-end microgrooves.
