G00?is?the?code?used?to?perform?rapid?traverse.?Rapid?traverse?is?used?for?quickly?positioning?the?tool?in?preparation?for?making?a?cut?or?moving?the?tool?to?a?safe?location?for?tool?and?part?change.?G00?can?be?used?any?place?where?the?tool?is?not?directly?in?contact?with?the?workpiece.?Rapid?traverse?is?never?used?to?perform?a?cut—the?velocity?is?far?too?fast?and?is?not?constant.?

In?addition?to?G-codes,there?are?a?number?of?codes?used?to?control?various?machine?functions?ranging?from?tool?change?to?coolant?control.?These?codes?are?called?miscellaneous?codes?or?simply?M-codes. M-codes?are?called?in?a?similar?manner?to?G-codes.?Many?M-codes?are?stand?alone?instructions?to?carry?out?some?function?such?as?turning?the?spindle?off.?A?few?M-codes?will?also?work?in?conjunction?with?other?address?to?perform?some?function.?For?example,the?code?to?turn?on?the?spindle?does?not?make?much?sense?unless?a?spindle?speed?has?been?entered?with?an?S?address. Tool?changes?are?accomplished?by?calling?the?M06?code.?After?the?tool?change,it?is?a?good?idea?to?turn?the?spindle?on?before?attempting?to?perform?any?metal?cutting.?This?is?accomplished?with?the?code?M03?and?M04.?M03?turns?on?the?spindle??in?clockwise(CW).?The?spindle?rpm?must?be?specified?in?the?same?line?or?in?a?previous?line.?M04?is?similar?to?M03,except?it?turns?on?the?spindle?in?counterclockwise. (中文翻譯見下頁) 事實(shí)上，所有的立銑刀，鉆頭，以及類似的工具，你會(huì)遇到是右撇子，因此使用M03。不過，也有情況下，當(dāng)左手切削工具的使用和您將需要使用M04。 冷卻劑也可與多個(gè)M代碼之一來控制。冷卻劑通常用在機(jī)加工操作，延長工具壽命，沖洗芯片遠(yuǎn)離，并改善表面粗糙度。 M08是用于接通冷卻劑系統(tǒng)上的一般的代碼。然而，M07可以使用洪水和霧冷卻劑系統(tǒng)上配備有兩個(gè)系統(tǒng)的機(jī)床之間進(jìn)行區(qū)分。 ? M09是用來關(guān)閉冷卻劑。這是一個(gè)很好的做法在換刀把冷卻液關(guān)閉以避免冷卻液噴到任何關(guān)鍵領(lǐng)域。它也把所述冷卻劑時(shí)關(guān)閉暫停中需要的程序，以檢查工具或工件的中間是一個(gè)好主意。 有許多情況下，您將需要執(zhí)行期間停止程序，以執(zhí)行一些任務(wù)。例如，您可能需要停止計(jì)劃，清理出的芯片切割區(qū)。 兩個(gè)代碼將自動(dòng)導(dǎo)致程序停止執(zhí)行：M00 M01和。首先，M00，是無條件的程序停止。當(dāng)控制讀取M00代碼，它將直到操作者再次按下循環(huán)啟動(dòng)按鈕停止所有軸的運(yùn)動(dòng)。該M01是有效的，只有當(dāng)控制面板上的可選停止按鈕被按下。 數(shù)控機(jī)床的軸向運(yùn)動(dòng)由一臺(tái)電腦，讀取程序，并指示多臺(tái)電機(jī)以適當(dāng)?shù)姆绞綄⒈灰龑?dǎo)。反過來電機(jī)使機(jī)床工作臺(tái)移動(dòng)和產(chǎn)生的加工零件。當(dāng)然，電腦不知道要砍，直到你寫一個(gè)程序來形容部分是什么形狀。 控制機(jī)床的想法電子是相當(dāng)簡單的。程序員編寫一組描述他或她是怎么想的機(jī)器移動(dòng)指令，并隨后把程序裝入機(jī)器的計(jì)算機(jī)。計(jì)算機(jī)讀取指令和將電信號(hào)發(fā)送到電動(dòng)機(jī)，然后把一個(gè)螺絲移動(dòng)機(jī)器表。安裝在工作臺(tái)上或電機(jī)上的一個(gè)傳感器發(fā)送定位信息返回給計(jì)算機(jī)。一旦計(jì)算機(jī)確定正確的位置已經(jīng)達(dá)到，接下來的舉動(dòng)將被執(zhí)行。 現(xiàn)代數(shù)控機(jī)床可以被編程為與一般被稱為G＆M代碼的語言進(jìn)行加工操作。 G代碼和M-代碼，程序員會(huì)寫，使機(jī)器的行為在一定的方式簡單的指令。 有幾十個(gè)G代碼和M代碼用于執(zhí)行一切從復(fù)雜的加工工序，以普通工具的變化。然而，短短的代碼將得到最所做的工作。其他的都只是增強(qiáng)使編程更加強(qiáng)大，并提供先進(jìn)的機(jī)器功能。 是用來控制和修改軸運(yùn)動(dòng)為加工和定位操作的代碼被稱為預(yù)備碼。它們被指定的字母“G”和通常簡稱為G代碼。有G代碼為許多不同的機(jī)器操作，包括定位，直線切割，圓形為切割，鉆孔作業(yè)，等等。 G00是用于執(zhí)行快速移動(dòng)的代碼?？焖僖苿?dòng)用于準(zhǔn)備快速定位工具制作一個(gè)切口或移動(dòng)刀具到安全位置的工具和零件的變化。 G00可以使用該工具不直接與工件接觸的任何地方。快速移動(dòng)決不會(huì)用來執(zhí)行剪切速度過于快，是不是恒定的。 G01是用于線性內(nèi)插的代碼。內(nèi)插是用于描述通過所有的點(diǎn)的過程的術(shù)語。如果直線插補(bǔ)，該工具將通過所有的點(diǎn)組成的直角直線坐標(biāo)系旅行。的G01代碼移動(dòng)從一點(diǎn)到另一點(diǎn)在指定速度的工具。 圓弧是加工的另一個(gè)共同特征。為了減少電弧，代碼G02 G03和用于圓弧插補(bǔ)。兩個(gè)代碼是在功能上是相同的，所不同的是G02將在順時(shí)針（CW）方向和G03在逆時(shí)針方向（CCW）方向切斷。 除了G代碼，還有一些用于控制各種機(jī)器功能，從換刀到冷卻液控制代碼。這些代碼被稱為雜碼或者干脆M代碼。 M代碼被稱為以類似的方式，以G代碼。許多M代碼是獨(dú)立的指令來進(jìn)行一些功能，如車削主軸關(guān)閉。幾M碼也將配合其他地址來執(zhí)行某些功能。例如，打開主軸上的代碼沒有太大意義，除非主軸轉(zhuǎn)速已進(jìn)入以S地址。 換刀通過調(diào)用M06代碼來實(shí)現(xiàn)。換刀后，它把主軸上嘗試執(zhí)行任何金屬切削之前是個(gè)好主意。這是通過在代碼M03和M04。 M03輪流在順時(shí)針主軸（CW）上。主軸轉(zhuǎn)速必須在相同的行上或在上一行中指定。 M04類似于M03，除了原來在逆時(shí)針的主軸上。
