事实上，它工作原理与巴贝奇的差分机相似，不同之处在于它的数字排列在圆柱形的外表面上而不是向织布机架那样水平分布。
In fact, it works much like Babbage's Difference engine, except that its digits are arrayed along the outer surface of a cylinder instead of horizontally along a loom-like rack.
所以，由此产生的机加工痕迹是一条具有很小节距的螺旋线，该节距等于进给。因此机加工表面始终是圆柱形的。
The resulting machining marks are, therefore, a helix having a very small pitch, which is equal to the feed. Consequently, the machined surface is always cylindrical.
