摘　　要：针对超精密车床提出一种新型的插补计算方法 ,将特殊精密曲线的插补功能集成到数控系统内部 。This paper introduces a new interpolation algorithm which is designed for ultra-precision CNC machining. It integrates aspheric curve interpolation function into CNC system instead of pre-processing aspheric curve out of CNC. General methods of error estimation by biarc curve-fitting and general methods of estimation of number of NC data block are also proposed..

关 键 词：曲线插补算法 超精密加工 数控加工 超精密车床
