using the real-time numeric control system as the controlling object, this dissertation designs the smallest network distributed manufacturing to test the ip multicasting and long-distance inspecting 實(shí)驗(yàn)表明:采用ip組播技術(shù)作為網(wǎng)絡(luò)通訊的手段時(shí),數(shù)據(jù)傳輸對(duì)網(wǎng)絡(luò)帶寬資源的占用不隨目標(biāo)節(jié)點(diǎn)的增多而成倍增加。
but it is designed by a new method and a new design thinking, as well as cpld is a new half-custom asic technology that will be used wider and wider . it is very significant to improve the numeric control system performance and enhance engineer design capacity 但作為設(shè)計(jì)控制系統(tǒng)的一種新方法和新思路,同時(shí)fpga作為一種半定制集成電路設(shè)計(jì)技術(shù)會(huì)越來(lái)越廣泛地被應(yīng)用,這對(duì)提高數(shù)字硬件系統(tǒng)設(shè)計(jì)水平和性能具有重要意義。
in order to improve the ability of aspheric optics manufacturing, a new cnc machine named asm is developed by ciomp, and its numeric control system is presents in this dissertation . the new machine has ability to fabricate off-axis " mirrors up to lm dimension, and the accuracy can reach up to 1 / 50xrms ( a . = 632.8nm ) 此外,文中還對(duì)新研制的六軸聯(lián)動(dòng)“asm數(shù)控非球面加工中心”的控制系統(tǒng)進(jìn)行了介紹,并專門(mén)介紹了加工中心在線輪廓測(cè)量單元中測(cè)量誤差的補(bǔ)償模型,以及與加工中心配套的控制軟件asm1.0的編制情況。
