回转类零件自由曲线CAD／CAM集成的实现

CURVE OF TURNED COMPONENTS CAD/CAM INTEGRATING

运用面向对象技术，研究了回转类零件中自由曲线ＣＡＤ／ＣＡＭ集成方法．在统一的数据模型基础上，实现了自由曲线形体从设计到加工的一体化，其中包括对给定的一系列离散点用Ｂ样条曲线进行拟合，刀具轨迹的生成。

A method for curves of turned components CAD/CAM integrating is presented in this paper by using the object oriented analysis technique. On the basis of the unified information model, curves of turned components are processed in an organic whole from designing to manufacturing, including B spline fitting and NC programming.
