Abstract

To improve machining efficiency and accuracy for surface, a method of machining Non-Uniform Rational B-spline (NURBS) surface based on IGES was put forward. The algorithms for surface information processing machining path planning and real time locus interpolation involved in this method have been worked out from the research results. A prototype of the CNC milling system with “PC+PMAC motion controller” is designed by toolpath planning, coordinate transformation and acceleration-deceleration control, which using VC ++ and openGL in Windows NT + RTX system platform. The simulation experiment was conducted to test the effectiveness and accuracy of the proposed method.
