id="4mkksekl" class="2">21世紀(jì)以來，由于科學(xué)技術(shù)的迅猛發(fā)展，工業(yè)自動化程度得到了空前進(jìn)步。數(shù) 控機(jī)床作為大批量、標(biāo)準(zhǔn)化、效率化加工工件的機(jī)械產(chǎn)品，其擁有量和技術(shù)水平是衡 量一個國家工業(yè)化、現(xiàn)代化的重要指標(biāo)。這不僅關(guān)系到國家在世界中的經(jīng)濟(jì)地位，更 體現(xiàn)一個國家科學(xué)技術(shù)的綜合實力。數(shù)控加工技術(shù)作為先進(jìn)制造業(yè)的神來之手，是 先進(jìn)制造系統(tǒng)中關(guān)鍵技術(shù)。隨著數(shù)控機(jī)床加工技術(shù)的發(fā)展和應(yīng)用，在確保產(chǎn)品質(zhì)量的 前提下，產(chǎn)品加工時間明顯減少，降低了產(chǎn)品的生產(chǎn)成本，產(chǎn)品的生產(chǎn)效率得到大幅 度得提升。隨著時代的進(jìn)步，科技工業(yè)得到跨越式的進(jìn)步，自動化程度和數(shù)控加工技 術(shù)也得到了質(zhì)的飛躍，人們對于數(shù)控機(jī)床的要求也到了前所未有的高度。現(xiàn)今社會人 們不但要求機(jī)械設(shè)備達(dá)到快速、高產(chǎn)、高自動化的要求，而且也要具有保護(hù)環(huán)境、節(jié)

擦，可以有效的提高零件的使用壽命，在節(jié)省能源方面具有重大的意義<sup>[2</sup>,<sup>3]</sup>。</span></p> <div><!--[endif]--> <div class="4mkksekl" id="ftn1"> <p class="a0"
