摘要

本校與合漢科技合作的陶殼模快速原型機，有許多未改善之處，本研究之目的為完成陶殼模快速原型系統自動化。
材料處理系統區可分為鋪層裝置與雷射掃描裝置兩部分，本研究僅改善鋪層裝置。於機構上加裝極限開關，安裝步進馬達，設計馬達治具等，讓鋪層裝置可以達到所需之功能。
控制系統是以製程電腦做為PC-BASE控制器，四軸運動控制卡主要是負責供料機構、鋪料機構、清料機構及精密Z軸平台之運動控制。而回授訊號處理卡則是負責處理光學尺之A、B兩相訊號，轉為數值資料後，使用人機介面檢測Z軸平台之定位準確性，完成閉迴路控制系統。此工作主要包含，配電箱設計、電路規劃，人機介面程式撰寫及設備測試等。
經實驗得知使用此快速原型系統，可讓Z軸平台的定位誤差減少到正負2μm，最薄可達到10μm之層厚，可達到精密鑄造的等級。

The beta system, which was developed with Lapex Technology co.,ltd., for making ceramic shell mold had many shortcomings. The aim of this study was for automation of this system.
The material handling system could be divided to layer paving device and laser scanning device. This study was focused on improving the layer paving device. The mechanism was add limit switches, installed stepping motor, and the fixtures for motor was design; therefore, the functions required by paving device could be achieved.
In control system, a computer was used for PC-BASE controller. A 4 axes control card was employed to control the material feeding mechanism, paving mechanism, material cleaning device and Z direction movement of platform. A feedback signal card was in charge of the A and B phases signal of linear scale; signal was transformed to digital data to inspect the accuracy of Z direction movement of platform, and then complete the close-loop control system. The work included control panel designing, electrical circuits planning, man-machine interface software designing and equipment testing.
According to the experiment results, the positioning error of Z direction movement of platform could be reduced to
