Analysis of Velocity Planning Interpolation Algorithm based on NURBS Curve.

To reduce interpolation time and Max interpolation error in NURBS (Non-Uniform Rational B-Spline) interpolation caused by planning Velocity .This paper proposed a velocity planning interpolation algorithm based on NURBS curve. Firstly, the second-order Taylor expansion is applied on the numerator in NURBS curve representation with parameter curve. Then, velocity planning interpolation algorithm can meet with NURBS curve interpolation. Finally, simulation results show that the proposed NURBS curve interpolator meet the high-speed and high-accuracy interpolation requirements of CNC systems. The interpolation of NURBS curve should be finished. [ABSTRACT FROM AUTHOR]
