异性螺杆在供送装置中有着非常重要的作用,并在石油、化工、像塑以及农机等行业的原料加工与供送中有着很广泛的应用,但异性螺杆的形状都比较复杂而且要求的精度也相对较高,这就导致了其制造灵活性的降低。本文就提出了集中异性螺杆的数学模型,并对其数控编程与加工工艺进行了一些研究,希望能够有效的解决通用数控机床加工此类零件的问题。 Heterosexual screw has a very important role in the feeding device and has a wide range of applications in the processing and delivery of raw materials in the petroleum, chemical, plastic and agricultural industries, but the shape of the opposite-shaped screw is more complex and the required accuracy It is also relatively high, which leads to a reduction in its manufacturing flexibility. In this paper, a mathematical model of concentrated heterosexual screw is put forward and some researches on its NC programming and processing technology are carried out. It is hoped that the problem of machining these kinds of parts will be solved effectively.
