为了获得供具有非均匀有理B样条(Non-Uniform Rational B-Sphne,NURBS)插值功能的CAD/CAM绘图和数控机床加工使用的设计数据,文中讨论了NURBS技术和平行分度凸轮轮廓曲线的三次NURBS表示方法,提出了用三次NURBS表示平行分度凸轮轮廓曲线后产生的设计误差的估计方法.

For the sake of obtaining the designing data to be used for CAD/CAM plotting and machining of numerical controlled machine tools that possessing the non-uniform rational B-spline (NURBS) function, the NURBS technology and the cubic NURBS expression method for the contour curves of parallel indexing cam were discussed in this paper. The estimation method of designing error produced in the contour curves of the parallel indexing cam to be expressed after using the cubic NURBS was put forward.
