【導(dǎo)讀】式自動(dòng)編程方法實(shí)現(xiàn)ＮＣ程序的編制。義互式編程是一種人機(jī)對話的編程方法，編程人員根據(jù)屏幕提示的內(nèi)容，反復(fù)與計(jì)算機(jī)對話，選擇菜單目錄或計(jì)算機(jī)的提問，將所有的問題回答完畢后即可以生生成ＮＣ程序。統(tǒng)對應(yīng)于不同的后處理文件。軟件當(dāng)前使用哪一個(gè)后處理文件，是在軟件安裝時(shí)設(shè)定的，而在具體應(yīng)用軟件進(jìn)。有些用戶在使用軟件時(shí)由于不了解情況，沒有對后處理文件進(jìn)行修改，導(dǎo)致生成的ＮＣ程序中某些固定的。行手工修改，如果沒有全部更正，則可能造成事故。例如，某機(jī)床的控制系統(tǒng)采用Ｇ５４工件坐標(biāo)系定位，Ｇ。勢必造成加工錯(cuò)誤。格式，也可以定義成ＦＡＮＵＣ６Ｍ控制器所使用的格式，但不能用來定義其它系列的控制器。所使用的刀具號(hào)碼。題時(shí)一經(jīng)使用，就會(huì)在生產(chǎn)的ＮＣ程序中表達(dá)確定的意義。假設(shè)在設(shè)定ＮＣ參數(shù)時(shí)所給的程序名為test1，（１２）當(dāng)使用者在換馬中使用權(quán)用next_tool變量時(shí)，問題１２０應(yīng)回答為"Ｙ"。當(dāng)后處理系統(tǒng)執(zhí)行時(shí)，
