本文根据机夹车刀刀具角度、刀槽几何参数和刀片刃磨角度之间的关系,提出了加工机夹车刀刀槽的新方法和计算步骤。条状刀片在这种新刀槽内可用到只剩下1/4的长度。挡屑板与刀片前面可组成不同的槽宽或槽形,因而使机夹车刀的刀片利用率更加充分,并能确保切削过程中断属或卷屑。实践表明,这种机夹车刀具有操作灵活,通用性好,切削轻快,断屑、卷屑可靠,刀片利用率高等优点,是金属切削中一种行之有效的先进刀具。 In this paper, according to the relationship between the tool turning angle, the geometric parameters of blade and the sharpening angle of the blade, a new method and calculation steps of the machining tool for turning the lathe tool are proposed. Only a quarter of the length is available for the strip blade in this new tool pocket. Chipboard and the front of the blade can be formed with different groove width or slot shape, so that the machine tool blade blade utilization more fully, and to ensure that the cutting process is cut or a chip. Practice shows that this machine folder turning with flexible operation, good versatility, cutting light, chip breaking, reliable chip roll, blade utilization advantages, is an effective cutting metal cutting tool.
