【正文】 加工信息，用規(guī)定的文字、數(shù)字和符號組成代碼，按一定的格式編寫成加工程序，然后將加工程序輸入數(shù)控裝置。 數(shù)控機(jī)床的組成 數(shù)控機(jī)床主要由數(shù)控系統(tǒng)、伺服系統(tǒng)、程序載體、輸入 \輸出裝置、強(qiáng)電控制裝置、輔助裝置和機(jī)床主體組成。 the horizontal moving device 。在本設(shè)計(jì)中， 刀庫橫移裝置的設(shè)計(jì)利用的是氣壓傳動機(jī)構(gòu)來實(shí)現(xiàn)刀庫的橫移運(yùn)動；而 刀庫分度裝置的設(shè)計(jì)利用的是槽輪機(jī)構(gòu)對刀盤進(jìn)行分度。 1 中文摘要
