摘要
网投影学自产生以来，就在正投影中得到了广泛的应用，并显示了强大的生命力，尤其在空间角度的计算上大大地提高了解题的速度．而在机器制造中，如机床夹具设计、刀具设计与制造、组合夹具拼装、机械加工时对零件的工艺计算等都会遇到大量的空间角度计算问题．随着计算机绘图技术的日益成熟，利用计算机绘制投影网，非常方便，并可极大地提高投影网的精度，如此必将促进网投影学更加广泛的应用．本文通过一些具体实例来加以说明．
In machine manufactory, the calculation of the dimensional angles is very difficult such as in the design of machine clamping apparatus, the design and manufactory of cutting tools, and the assembling of assorted clamping apparatus. However the web-projection techniques can make the calculation of the dimensional angles faster and has been used widely in vertical projection. Especially, as the development of computer drawing, it is very convenient to drawing a projection web, and it can also improve the precision of the projection web. This paper will give some applications of web-projection techniques in mechanical manufactory.
