【導(dǎo)讀】在泰國工業(yè)上所用的大部分數(shù)控機床都是進口的。經(jīng)過定期的保養(yǎng)，這些數(shù)?？貦C床的使用壽命可長達10年。在到達使用壽命以后，公司一般會買一臺新機器?；蚋脑炫f的機器，后來這種過程被統(tǒng)稱為“改造”。技術(shù)因此改造通常的花費也不少。此外，經(jīng)過10年使用后停產(chǎn)的大多數(shù)機床將使。改造費用更昂貴或幾乎不可能再改造。這樣的問題也存在于教育機構(gòu)，例如泰國。造400臺已用了10年的機床。其中大部分的機床需要新的曾長期停用的工業(yè)運動。因此，基于開放式結(jié)構(gòu)和模塊化的工業(yè)用數(shù)控機床運動控制系統(tǒng)已經(jīng)被。用戶可以輸入G代碼進行控制，監(jiān)控機床的狀態(tài)或者在執(zhí)行G代碼之前進行模擬。發(fā)送信息進行通訊和控制?；蚶鋮s液開關(guān)、利用運動控制卡在手輪和緊急開關(guān)通訊之間的轉(zhuǎn)換。指令都經(jīng)由雙埠RAM被連續(xù)傳送到運動控制卡。狀態(tài)、當前G代碼狀態(tài)和刀具軌跡的圖像顯示。渠道接受來自于MMI的指令?，F(xiàn)場試驗的初步結(jié)果是令人滿意。的，這兩臺銑床現(xiàn)又恢復(fù)正常運行。
【正文】 tween them. NC module generates continuous straight or curved trajectory for continuous movement, with higher performance than pointtopoint control 4. FIELD TEST Test System Installation The developed prototype system is suitable for 3axis milling machines that have industrial type motor drives supporting analog control signal (177。 10 V). The retrofitting system requires limit switch and home switch installation connected directly to the motion control card. Other remaining devices such as key panel, spindle, and coolant are connected to the external I/O Module. Test Results After several successful tests in laboratory, the described system has been pleted and installed at two Vocation Technical Colleges for field testing. The systems are installed on a local model ， The model’s mechanical ponents were locally manufactured with a plete import motion control system installed. After about 10 years of usage for training students, the original mechanical ponents and motor drive systems are in good condition and the only part that requires replacement is the motion controller which also had been discontinued. Two milling machines were retrofitted using the developed motion control system for both MMI and the motion control card. The preliminary field test results are satisfactory where both machines resume their normal operation. However, longer operating hours are needed to evaluate the product full potential and to improve system stability. 4. CONCLUSION The research project for developing the motion control card for retrofitting old milling machines is an attempt for sustainable technology development. The industrial grade CNC motion control prototype system has been successfully developed and two CNC machines have been installed for field test. The project first aims at restoring old CNC machines at Thai Vocational Technical Colleges that require new industrial motion control cards which had been long discontinued and eventually expect its usage for retrofitting other old machines in local industry. 第 7 頁 共 7 頁 指 導(dǎo) 教 師 評 語 外文翻譯成績： 指導(dǎo)教師簽字： 年 月 日 注： 1. 指導(dǎo)教師對譯文進行評閱時應(yīng)注意以下幾個方面：①翻譯的外文文獻與畢業(yè)設(shè)計（論文）的主題是否高度相關(guān)，并作為外文參考文獻列入畢業(yè)設(shè)計（論文）的參考文獻；②翻譯的外文文獻字數(shù)是否達到規(guī)定數(shù)量（ 3 000 字以上）；③譯文語言是否準確、通順、具有參考價值。 2. 外文原文應(yīng)以附件的方式置于譯文之后。8 頁 共
