| Abstract: | To improve machining efficiency and accuracy for free-form surface,a method of machining Non-Uniform Rational B-Spline(NURBS) surface based on STEP-NC was put forward.By using this method,Computer Numerical Control(CNC) could deal with NC program which consisted of NURBS surface geometry data and machining technology data in the form of STEP-NC.Interpolation algorithm for NURBS surface was developed.Finally,simulation experiments were provided to verify the effectiveness of the proposed method. |
