140CPS12400數(shù)據(jù)庫,模塊
加工中心的機(jī)床的刀具庫容量可達(dá)到100多把刀,自動(dòng)換刀裝的換刀時(shí)間僅需0.5-2秒。加工中心機(jī)床使工序集中在一臺(tái)機(jī)床上完成,減少了由于工序分散,工件多次安裝引起的定位誤差,提高了加工精度,同時(shí)也減少了機(jī)床的臺(tái)數(shù)與占地面積,壓縮了半成品的庫存量,減少了工序間的輔助時(shí)間有效地提高了數(shù)控機(jī)床的生產(chǎn)效率和數(shù)控加工的經(jīng)濟(jì)效益。
140CPS12400數(shù)據(jù)庫高速,高效,高精度是機(jī)械加工的目標(biāo),數(shù)控機(jī)床因其價(jià)格昂貴,在上述三個(gè)方面的發(fā)展也更為突出。
數(shù)控機(jī)床制造產(chǎn)把建立有好的人機(jī)界面,提高數(shù)控機(jī)床的可靠性作為提高競爭能力的主要方面。
(4) 手工編程和自動(dòng)編程已經(jīng)使用了幾十年,有了長足的發(fā)展,在手工編程方面,開發(fā)了多種加工循環(huán),參數(shù)編程和除直線,圓弧意外的各種插補(bǔ)功能,CAD/CAM的研究發(fā)展,從技術(shù)上來講可以替代手工編程,但是一套適用的CAD/CAM軟件加上計(jì)算機(jī)硬件,投資較大,學(xué)習(xí),掌握的時(shí)間較長,對大多數(shù)的簡單工件很不經(jīng)濟(jì)。
今年來,發(fā)展起來的圖形交互式編程系統(tǒng),很受用戶歡迎。這種編程方式不使用G,M代碼,而是借助圖形菜單,輸入整個(gè)圖形塊以及相應(yīng)參數(shù)作為加工指令,形成加工程序,與傳統(tǒng)加工時(shí)的思維方式類似。圖形交互編程方法在制定標(biāo)準(zhǔn)后,有可能成為各種型號的數(shù)控機(jī)床統(tǒng)一的編程方法。第一節(jié) 零件圖的工藝分析
在設(shè)計(jì)零件的加工工藝規(guī)程時(shí),首先要對加工對象進(jìn)行深入分析,對于數(shù)控車削加工應(yīng)考慮以下幾個(gè)方面
1 構(gòu)成兩件輪廓的幾何條件
在車削加工手工編程時(shí),要計(jì)算每個(gè)節(jié)點(diǎn)坐標(biāo),在自動(dòng)編程時(shí),要對零件輪廓所以的幾何元素進(jìn)行定義,因此在分析零件圖時(shí)要注意
(1) 零件圖上是否漏掉某尺寸,使其幾何條件不充分,影響到零件輪廓的構(gòu)成。
(2) 零件圖上的圖線位置是否模糊或標(biāo)注不清,使編程無法下手
(3) 零件圖上給定的幾何條件是否不合理,造成數(shù)學(xué)處理困難
(4) 零件圖上的尺寸標(biāo)注方法應(yīng)適應(yīng)數(shù)控車床加工的特點(diǎn),應(yīng)以同一基準(zhǔn)標(biāo)注尺寸或直接給出坐標(biāo)尺寸smart city and Internet of things are the huge driving factors driving the industrial switch Market in the future. They are expected to integrate a series of application industries such as transportation, industry and security through communication connection, resulting in huge demand for industrial switches. In the early industrial network products, most of them focused on the electrical, physical, structural and other characteristics of industrial switches. Nowadays, in addition to the standardization of previous hardware conditions, with its development towards intelligence, flexibility and efficiency, industrial networks pay more and more attention to software features such as network management, ring network switching, redundancy, QoS and platform. Industrial switch products not only strictly comply with industrial standards in the selection of product components and raw materials, but also establish many advantages in the richness and perfection of software functions. It provides perfect solutions in power, transportation, energy and other industrial fields.
