DSP Curve Surface Interpolator Research Based on Open Platform


Article Preview

For the improvement of the system real-time capability, the DSP Curve Surface interpolator has been designed to ensure high speed, high precision requirement for the machining of complexity curve surface. The hardware and software has been designed. The changeable feedrate interpolation algorithm of limit curve error has been studied. Furthermore, the algorithm has been applied to the interpolation and has well real-time capability to satisfy the requirement of high capability CNC by experimentation.
