摘 要
隨著計(jì)算機(jī)業(yè)的快速發(fā)展，數(shù)控技術(shù)也發(fā)生了根本性的變革，是近年來應(yīng)用領(lǐng)域中發(fā)展十分迅速的一項(xiàng)綜合性的高新技術(shù)。
數(shù)控技術(shù)是關(guān)鍵技術(shù)，它集微電子、計(jì)算機(jī)、信息處理、自動(dòng)檢測(cè)、自動(dòng)控制等高新技術(shù)于一體，具有高精度、高效率、柔性自動(dòng)化等特點(diǎn)，對(duì)制造業(yè)實(shí)現(xiàn)柔性自動(dòng)化、集成化、智能化起著舉足輕重的作用。
數(shù)控技術(shù)中的數(shù)控編程是數(shù)控機(jī)床按照事先編制好的加工程序，自動(dòng)地對(duì)被加工零件進(jìn)行加工。我們把零件的加工工藝路線、工藝參數(shù)、刀具的運(yùn)動(dòng)軌跡、位移量、切削參數(shù)(主軸轉(zhuǎn)數(shù)、進(jìn)給量、背吃刀量等)以及輔助功能(換刀、主軸正轉(zhuǎn)、反轉(zhuǎn)、切削液開、關(guān)等)，按照數(shù)控機(jī)床規(guī)定的指令代碼及程序格式編寫成加工程序單，再把這程序單中的內(nèi)容記錄在控制介質(zhì)上(如穿孔紙帶、磁帶、磁盤、磁泡存儲(chǔ)器)，然后輸入到數(shù)控機(jī)床的數(shù)控裝置中，從而指揮機(jī)床加工零件。
目前許多國(guó)家對(duì)開放式數(shù)控系統(tǒng)進(jìn)行研究，數(shù)控系統(tǒng)開放化已經(jīng)成為數(shù)控系統(tǒng)的未來之路。所謂開放式數(shù)控系統(tǒng)就是數(shù)控系統(tǒng)的開發(fā)可以在統(tǒng)一的運(yùn)行平臺(tái)上，面向機(jī)床廠家和最終用戶，通過改變、增加或剪裁結(jié)構(gòu)對(duì)象（數(shù)控功能），形成系列化，并可方便地將用戶的特殊應(yīng)用和技術(shù)訣竅集成到控制系統(tǒng)中，快速實(shí)現(xiàn)不同品種、不同檔次的開放式數(shù)控系統(tǒng)，形成具有鮮明個(gè)性的名牌產(chǎn)品反映了數(shù)控機(jī)床加工向網(wǎng)絡(luò)化方向發(fā)展的趨勢(shì)。

關(guān)鍵詞：數(shù)控技術(shù)；數(shù)控編程； 智能； 發(fā)展趨勢(shì)







Abstract
With the rapid development of the computer industry, digital technology has undergone a fundamental change, application areas in recent years developed very rapidly in a comprehensive high-tech.
CNC technology is the key technology, which combines micro-electronics, computer, information processing, automatic detection, automatic control and other high-tech in one, with high precision, high efficiency, flexibility and automation features, the flexible manufacturing automation, integration, intelligent technology plays a pivotal role.
CNC Technology CNC CNC programming is pre-programmed in accordance with processing processing parts being automatically processed. We machining process route, process parameters, tool trajectories, displacement, cutting parameters (spindle rpm, feed rate, volume, fed knife, etc.) and auxiliary functions (ATC, spindle forward and backward, cutting fluid opening and closing, etc.), in accordance with the provisions of CNC machine tools and procedures for the instruction code format of processing into a single, then this procedure a single content recorded in the control medium (such as perforated paper tape, tape, disk, magnetic bubble memory ),
Then, entered into the CNC machine tool numerical control device which commands machining parts.
At present, many countries of open CNC system, CNC system has become open and the Future of CNC. The so-called open CNC system is the development of numerical control system can be run in a unified platform for Jichuang manufacturers and end users, by changing, adding or cutting structure of objects (NC function) to form a series, the user can easily special applications and technical know-how into the control system, fast implementation of different varieties and different grades of open CNC system, forming a distinctive brand personality reflects the CNC machine to the network develop in the direction of the trend.
Key words: numerical control technology; NC programming; intelligent;
