Abstract
To meet the requirement of exploring a new generation of CNC systems based on STEP-NC, NURBS interpolation has been studied. In contrast to existing NURBS interpolation based on the Taylor’s expansion, this paper proposes a new method for NURBS interpolation which is based on exponential smoothing forecasting. The new method is very simple; it decreases the computational load observably, and speed and precision control are also achieved. This paper presents relative formulas and main computational processes, including speed and precision control, computation of real-time mapping, computation of real-time track, etc. The simulation results indicate that the method is feasible and has high-precision and better real-time performance, which is sufficient for the STEP-NC system.
