style="text-indent:25px">在汽車制造過程中，普遍地采用鍛造的加工方法。鍛造分為自由鍛造和模型鍛造。自由鍛造是將金屬坯料放在鐵砧上承受沖擊或壓力而成形的加工方法(坊間稱“打鐵”)。汽車的齒輪和軸等的毛坯就是用自由鍛造的方法加工。模型鍛造是將金屬坯料放在鍛模的模膛內(nèi)，承受沖擊或壓力而成形的加工方法。模型鍛造有點像面團在模子內(nèi)被壓成餅干形狀的過程。與自由鍛相比，模鍛所制造的工件形狀更復(fù)雜，尺寸更精確。汽車的模鍛件的典型例子是：發(fā)動機連桿和曲軸、汽車前軸、轉(zhuǎn)向節(jié)等。</p><p style="text-indent:25px">國內(nèi)外企業(yè)選擇高速切削刀具參數(shù)和高速切削加工參數(shù)的方式仍以傳統(tǒng)的“試切法”和“經(jīng)驗法”為主。在加工某一新型材料時，往往需要使用多種刀具進行重復(fù)切削試驗，研究分析刀具的磨損、破損方式及其原因，從中找出一組比較好的刀具材料和加工參數(shù)，如此反復(fù)多次，盲目性大，并且浪費大量的人力、財力和資源。而針對特種材料如合金鑄鐵、高強度合金鋼、超級合金（如鈦合金）等材料的高速切削加工，如何根據(jù)材料特性選擇合適的切削刀具，如何設(shè)計合理的切削參數(shù)，目前仍在研究和發(fā)展中。高速切削加工技術(shù)的應(yīng)用極大提高了汽車模具的開發(fā)速度。</p><div
