NURBS在微机控制球面轴承内套双沟一次磨削加工中的应用

The application of NURBS to once-through grinding for double raceways of spherical inner ring

球面内套双沟道一次磨削加工技术对保证对称球面加工精度、提高粗糙度水平和磨削效率均为有利，是提高球面轴承等机械产品加工质量和生产效率的先进技术手段［１］。本文介绍应用 ＮＬＵＲＢＳ技术实现在对砂轮修整中的数字插补控制方法。

The once-through grinding technique for double receways of spherical inner ring is very valuable to guarantee the machining accuracy of symmetric spheres,and to improve the roughness and grinding effeciency, which is the advanced technical method for enhancing the machining qualiyt and production effeciency of spherical bearing or other machinery producta. In this paper,we will introduce the once-through grinding method, corresponding NURBS method and the interpolation control technique in the course of grinding wheel dressing.
