| Abstract: | STEP - NC is a new interface standard, which is being used as the basis for the next generation of CNC controller. In the new CNC system, not only linear or arc but also splines can be interpolated. An universal interpolation employing NURBS is designed and a algorithm to process NURBS data is developed,as well as the interpolation technology based on constant arc increment is also discussed in detail. Finally validity and reliability of the algorithm is tested by a simulation and instance machining. |
