用标准平铣刀加工工件,表面光洁度只能达_3。要想再提高表面光洁度,需要经过磨削;由于我们缺乏磨床,所以只好用钳工修锉,因而生产率很低,不能满足需要。后来我们就从刀具几何形状上着手,通过几次试验证明:改变铣刀的几何形状,可以提高工件表面光洁度。 1.改进平铣刀几何形状:平铣刀的几何形状主要是按照科列索夫车刀的原理改进的。我们知道,科列索夫车刀除了有一个主切削刃外,还有一个平行刃,也叫修光刃。修光刃主要是起修光作用,也就是主切削刃切过之后,通过修光刃重复一次
With a standard flat cutter workpieces, surface finish can only reach _3. To further improve the surface finish, it needs to be ground. Due to our lack of grinder, we had to file with a fitter, resulting in a very low productivity that could not be met. Later, we started with the geometry of the tool. Several tests proved that changing the geometry of the milling cutter can improve the surface finish of the workpiece. 1. Improve the geometry of flat cutter: The geometry of flat cutter is mainly improved according to the principle of Koleasov. We know that Koleasov tool in addition to a main cutting edge, there is a parallel blade, also known as wiper. Wand repair is mainly from the role of repair, that is, after cutting the main cutting edge, the wiper is repeated
