圆柱螺旋线
cylindrical spiral
[数] circular helix
[数] circular helix
- 用复合函数的形式，导出导程呈线性变化的圆柱螺旋线的参考方程。
In the form of function of functions this article derives the parametric equation of cylinder helix the lead of which is of a linear change. - 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. - 本文提出沿圆柱表面的螺旋线对圆柱度作动态测量，并应用最佳一致逼近方法对其展开的测量数据来评定圆柱度误差值。
This paper presents a method to evaluate cylindricity errors. It uses best uniform approximation to process the sample data measured continually and dynamically along a cylindrical spiral.
