摘要
分析了NURBS(Non-Uniform Rational B-Spline)曲线直接插补技术相对于传统数控系统中采用的直线或圆弧逼近对NURBS曲线数控编程的优越性;探讨采用NURBS曲线插补技术的CNC机床曲线曲面的加工方法以及实际应用中需要进一步解决的问题。
Analyzed the advantages of technology of NURBS(Non-Uniform Rational B-Spline) curve interpolation comparing to traditional CNC system which uses approaching method for NURBS curve NC programming,Introduced the processing method of curve and curvilinear surface by CNC machine which use the NURBS curve interpolation.At last,put forward some problems in practical process.
