此外脈沖穿孔還需要有較可靠的氣路控制系統(tǒng)，以實現(xiàn)氣體種類、氣體壓力的切換及穿孔時間的控制。在采用脈沖穿孔的情況下，為了獲得高質(zhì)量的切口，從工件靜止時的脈沖穿孔到工件等速連續(xù)切割的過渡技術(shù)應(yīng)以重視。從理論上講通?？筛淖兗铀俣蔚那懈顥l件：如焦距、噴嘴位置、氣體壓力等，但實際上由于時間太短改變以上條件的可能性不大。在工業(yè)生產(chǎn)中主要采用改變激光平均功率的辦法比較現(xiàn)實，具體方法有以下三種：⑴改變脈沖寬度；⑵改變脈沖頻率；⑶同時改變脈沖寬度和頻率。實際結(jié)果表明，第⑶種效果好。激光切割關(guān)鍵技術(shù)二噴嘴設(shè)計及控制技術(shù)激光切割鋼材時，氧氣和聚焦的激光束是通過噴嘴射到被切材料處，從而形成一個氣流束。對氣流的基本要求是進入切口的氣流量要大，速度要高，以便足夠的氧化使切口材料充分進行放熱反應(yīng)；同時又有足夠的動量將熔融材料噴射吹出。因此除光束的質(zhì)量及其控制直接影響切割質(zhì)量外，噴嘴的設(shè)計及氣流的控制（如噴嘴壓力、工件在氣流中的位置等）也是十分重要的因素。如今激光切割用的噴嘴采用簡單的結(jié)構(gòu)，即一錐形孔帶端部小圓孔。通常用實驗和誤差方法進行設(shè)計。由于噴嘴一般用紫銅制造，體積較小，是易損零件，需經(jīng)常更換。</p><p> 板材切割常用方式有手工切割、半自動切割機切割及數(shù)控切割機切割。手工切割靈活方便，但手工切割質(zhì)量差、尺寸誤差大、材料浪費大、后續(xù)加工工作量大，同時勞動條件惡劣，生產(chǎn)效率低。半自動切割機中仿形切割機，切割工件的質(zhì)量較好，由于其使用切割模具，不適合于單件、小批量和大工件切割。其它類型半自動切割機雖然降低了工人勞動強度，但其功能簡單，只適合一些較規(guī)則形狀的零件切割。數(shù)控切割相對手動和半自動切割方式來說，可有效地提高板材切割地效率、切割質(zhì)量，減輕操作者地勞動強度。在我國的一些中小企業(yè)甚至在一些大型企業(yè)中使用手工切割和半自動切割方式還較為普遍。我國機械工業(yè)鋼材使用量已達到3億噸以上，鋼材的切割量非常大；隨著現(xiàn)代機械工業(yè)的發(fā)展，對板材切割加工的工作效率和產(chǎn)品質(zhì)量的要求也同時提高。因而數(shù)控切割機的市場潛力還是很大、市場前景比較樂觀。[2]切割機現(xiàn)狀1、經(jīng)過幾十年的發(fā)展，數(shù)控切割機在切割能源和數(shù)控控制系統(tǒng)兩方面取得了長足的發(fā)展，切割能源已由單一的火焰能源切割發(fā)展為多種能源(火焰、等離子、激光、高壓水射流)切割方式?？死斠楞@孔切割公司。</p><div
