碩士 === 國立交通大學 === 機械工程系所 === 93 === Mutiple axes motion control system is primary and important control algorithms for improving to generate motion commands on CNC machine. In the early researches, the DDA algorithms is used widely to generate the cutting path commands. In this thesis, the Bicubic DDA algorithms is designed and implemented for 3D space motion control, and practiced in open-loop system architecture. By mapping 3D cutting contour in each axis, the Bicubic DDA algorithms is easy to be practiced in an embedded system, which including in high-performance DSP with real-timeµμC/OS-II kernel and programmable FPGA chip. For the advantage of the low-cost, convenient and domesticable feature of embedded system, the 3D space motion command is implemented for real-time motion control.
