The system is based on an open architecture PMAC (Programmable multi-Axis controller) motion control card to realize real-time control. Some experiments concerning control test and error measurement and analysis can be carried out on the designed worktable. At first, the configuration of control system of the 3D NC worktable Was proposed ,and its software was developed. Modular software development concept featured the system design, which includes the following modules: machining position and speed sampled display module; file management module; parameters setting module; error diagnosis module; precision analysis module; manual debugging module; machine simulation module; help module.As one of focuses, the error measurement and precision analysis of the worktable were emphasized in the development of the system software. Series of experiments about system control and precision were made on the worktable. The precision characteristics of the half-loop and closed-loop position feedbacks were analyzed. Through comparing the theoretical analysis with the data collected from experiments ,a conclusion has been drawn that the smallest contour error will be got if the two axes have the same servo characteristics. The ball-bar ,which is considered to be more reliable than linearscales in measuring contour error, was used to measure the circular motion of the system. The experiment result showed that the contour error of the system was big .By analysis of the error source based on a mathematical model of the measuring system proposed in this thesis, it was found that it was the installation inclination of linear scales that caused so big error. By compensating the error with the measured result by the ball-bar ,the precision of the control system had been improved.Keywords Numerical Control System；three-dimensional NC workbench；SCM；Interpolation technique；III目錄摘要IAbstractII第1章 緒論11.1課題研究的意義11.2課題研究的現狀11.3課題研究的主要內容2第2章 三維數控工作臺的硬件選擇及連接結構32.1三維數控工作臺的工作原理介紹32.2三維數控工作臺的基本結構32.3步進電機的選擇42.4絲杠的選型與校核52.4.1滾珠絲杠的簡單介紹52.4.2滾珠絲杠的選型72.4.3滾珠絲杠的校核82.5直線導軌的選型與計算92.5.1直線導軌的簡單介紹92.5.2直線導軌的選型102.6聯軸器的選型122.6.1聯軸器的簡介122.6.2聯軸器的選型132.7軸承選型142.8本章小結16第3章 三維數控工作臺的Pro/E三維建模173.1 Pro/E建模軟件簡介173.2 Pro/E界面介紹173.3零件三維建模實例介紹183.3.1新建文件183.3.2建立拉伸特征193.3.3建立螺旋特征203.3.4建立螺母副特征203.3.5進行顏色和外觀設計213.4其余零件三維建模圖展示223.5三維數控工作臺裝配233.6本章小結25第4章 三維工作臺的軟件及控制系統設計264.1逐點比較法直線插補的簡介264.2逐點比較法直線插補的計算步驟264.3數控插補仿真軟件的說明294.4開環(huán)系統控制原理304.5單片機設計304.6本章小結35結論36致謝37參考文獻38附錄一39附錄二492
