摘要
用接触式量仪测量曲面，通常得到的测量数据是实际曲面的等距曲面。等距曲面的一般理论是ＣＡＧＤ中有待探索的热门课题，螺旋面却是一个简单的特例：螺旋面的等距曲面也是螺旋面。本文作者运用螺旋线的偏置曲线的理论证明这个命题。以此为依据可使螺旋面测量数据的处理简便易行。
In contact measuring of a free surface, the data delivered construct an equi-distant offset of the measured surface. The general theory about offset surfaces is a topic under intensive study. But the screw surface is a special case, i.e. the equi-distant surface of a screw surface is a screw surface also. By avail of the offset curve theory, this proposition is proven. Thus the data treatment for screw surface measurement is simplified.
