在铣床上用标准直齿三面刃铣刀加工时,当切削宽度接近或等于铣刀宽度和加工较深的沟槽时,由于刀具与工件接触面积较大,易使切削力增加并引起机床颤动、切削中排屑不畅以及刀具磨损加剧等。这样,在加工时就直接影响了生产效率和加工质量,特别是表面光洁度较低。针对以上问题,经过多次试验,我们发现,把标准直齿三面刃铣刀,改制成分屑三面刃铣刀
In the milling machine with a standard straight three-sided milling cutter, when the cutting width close to or equal to the milling cutter width and depth of the groove, due to large contact area of the tool and the workpiece, easy to increase cutting force and cause machine vibration , Cutting poor chip removal and tool wear and so on. In this way, when processing directly affects the production efficiency and processing quality, especially the surface finish is low. In response to the above problems, after many tests, we found that the standard straight three-sided cutter, restructuring into three-edged chip cutter
