    Abstract: 過去自動化系統整合上,常見二大問題:1.連續加工的抽驗尺寸,導致不良品整批報廢損失。2.加工品良率一直無法有效明顯提升。為了改善其問題,本論文建立相關定位量測應用平台。並針對輪圈加工製程,開發設計視覺定位搭配雷射量測應用,與線外量測補償之軟硬體,分析最佳夾持點與誤差補償進行加工,達到成品良率提升之目的。在開發應用主要分為三部份,第一:供料定位,以視覺辨識與伺服控制系統,結合人機介面軟體技術開發,完成自動化之定位應用。第二:最佳夾持點,以雷射測距搭配線性馬達控制系統,結合數據分析與CNC通訊,進行夾持多角度定位,完成原料最佳放置點之開發應用。第三:線外量測,對成品進行雷射測距之數據分析,完成相關刀具數據補償與成品全檢。另外,藉由大量的數據收集與分析,將可提供更可靠的製程改善,達到降低不良率之目的。
    In the past, there were two common problems with automation system integration. The first one is to perform spot check during the generating process which usually causes defected items. The defected items must be discarded. The second one is to increase the yield rate which was not been improved during the past years. In order to resolve the problems, this study tried to establish a positioning measurement platform. At the same time, I developed the visual positioning system with laser measurement The hardware and software are built for off-line measurement compensation during rim finishing process. I tried to analyze the best nipping point and performed error compensation for processing, and thus the yield rate can be enhanced. The development process can be divided to 3 parts. First, I used visual identification, servo control systems and human-machine interface software technology to complete the automatic positioning system. Second, the laser ranging with linear motor control system, data analysis and CNC communication is used to find out the best product nipping point of the raw material. Third, I used laser ranging to analyze finished product, completed the relevant tool data compensation and finished product inspection. In addition, with a large amount of data collection and analysis, the data could be used to further improve the process, and enhance the yield rate.
