摘要

數值控制在工具機上的使用是相當重要的一環，然而，在一般成本較低廉的工具機卻使難以實現。在本論文中，利用單晶片輔助可程式控制器的方式，建立數值控制系統。

而達到數值控制需要提供以下三大功能：數值顯示、功能按鍵的選擇、及位置控制的功能。在數值顯示方面，使用者利用此功能才能得知目前機台的狀態。利用簡單的七段顯示器達到顯示數值方面的資訊，並研究如何透過可程式控制器的I/O繼電器達到顯示功能。在按鍵功能中，使用者可以利用此功能去輸入機台內部的數值功能。在本論文中，將提供了如何整合數值顯示及按鍵功能的方法。

另外，利用單晶片及可程式控制器之間的整合來達得平面磨床上的閉迴路控制是值得研究的，因為單晶片微處理機將會因其高速計算及處理的能力，使得系統可以達到閉迴路控制功能，另外，可程式控制器在各種I/O控制、監控及順序控制上有高穩定的優點。本研究利用理論推導後的結果，實際建立系統，而最後模擬的結果及實際建立的系統都可以滿足系統的需求。

Numerical control is important in the machine tool. However, it is not feasible in low-cost machines. In this article, the programmable logic controller in association with the single chip microprocessor is selected as an example, to built up the numerical control system.

There are three main functions in the numerical control system: numerical display, function key, and position control. In numerical display function, the user can use this information to know the status of the machine. The simple seven-segment display is used to display the numerical information. In connection with the PLC as well as the I/O relay is investigated. The user can use the function key to input the numerical data in the machine. The integration of the numerical display and function key is presented in this article.

Integration of microprocessor and programmable logic controller for closed-loop position control design of surface grinding machine is studied. The single chip microprocessor is in charge of the feedback control because of its merit of high-speed computation and processing. The programmable logic controller takes the advantage of high reliability is used to manage various tasks of I/O, monitoring and process control. Control system design is accomplished with both the theoretical approach and practical implementation. The simulation and practical experiment verify the developed controller is able to satisfy the system requirement
